I find it weird when me and my alliance member played in the same Scarlet Witch arena. I got rank 12922 with 378376 points whereas my friend rank 245 with 370000 points but he end up got Scarlet Witch and I don't.

Heck, even the 2nd top player in which my alliance member played is krit79 and in my arena is martijn & mike? Why the different? Did they divide by region or something?

We will be going to have a 5*.

And I don't even have 4*.

... for new gamers, these lower cards are what you started with.  You build your teams from these.

First you build your 2* rosters.  When I started the game, 160k looked daunting.  I could barely scratch 90k in the 3* arena.  Now I could do 300-400k in a day if I really grind.  If I paced myself, I could easily do 180k daily between breaks - enough to earn a 3*.  Until now my roster is not good enough for 4* arena but i am getting there.  I will not talk about 4* roster.  Not yet.

For the longest time I have a SINGLE 4* I could not promote pass rank 2.  My point is that 4* does not do much for you in an arena unless you could get many of those.  The game is not designed that way.  There is no short cut to it.  You could not hack to it. You have to spend tons of money to quickly acquired the 4* roster, or you go the painful way - opening crystals and doing arenas.  Obviously lots of these as the drop rate is abysmal and the cutoff is ridiculous.

Yes, 4* is good for quests.  So does your maxed 3*.  My advise is play the game but do not expect instant gratification.  Keep your units.  Do not use your units to buy crystals even the 3* other than 4*.  Farm the premium crystals PC instead.  Leisurely you could get 4-5 PCs every week from arena milestones and crystal cornucopia, more if you grind hard.  If you desire the 3*, they are in the arena reward or PCs at about 3-4% drop rate.  Build your 3* roster from there - no need to use units for the 3* crystals.  Use your units ONLY for 4* crystals or 5* when time comes.

I see a more layered platforms coming.  You could stay in your comfort zone and play casually - not in the competitive arena or demanding alliance, which is still enjoyable enough for passing time. 

Otherwise you just have to work your way up or if you are tired of it, get out...

Wow, you 100% Thanos already.... I just did one run.... to test water..... Look like need to rank up my 4 star as seem all 3 star team even awaken is not gonna cut it unless you willing to use revive and health all the way with Thanos...
Got 1 more alpha to spent... now choosing which 4 star to rank up... Gamora, Starlord or Dr Strange... all not awaken...
unless I concentrate on the Basic Catalyst Arena and bring my Colussus to rank 4/5.. mmmmmmm.

Just got him recently, from a PC. So the nice doctor now still at 1/5 same as Starlord that come from PC somewhere along the Ultron Quest and the Leader of Guardian of the Galaxy also still at 1/5. Both come recently while my other 2 4star had been with me for the longest time. Colussus came with Second Skin when I started when the games was launch in December and along come Gamora quite early in the game think somewhere when alliance started. These 2 4star really help me in the Quest early in the games. Rank up my Colussus to 3/5 when I got my first alpha free from Kabam and still have my 2nd alpha won during the Ultron Quest. Now waiting for the 3rd Alpha from Antman.
Most of my ISO spent on my 3 star team for questing and building a few strong team of 2 star for the Arena. I can now comfortably choose which 2* Arena to participate and win my favourite 3*. Now buiding my 3* for the 4* Arena.
Yeah, now letting Thanos rest.... need to work in the Alliance with my alliance member.....
Go go [LWF] Lowyat Alliance........

Come come .. join my alliance.. we get addicted together.... hahaha

... for a guy who sucks at MCoC, you seem to take great interest in the game.  Glad you enjoy your new mobile game, but please let's enjoy our game without you trying to belittle it every now and then.  We know you could not get ahead and give up.  Just let it go will ya.

Kabam messes up AGAIN with the recent 7 day event.  Gazillioin point for a watered down 4* Caps.  Give us a break.  Our alliance is not even attempting this event, individually most of us do get up to +3mil milestone, probably to 6mil over the days but not much more.  The rank reward also is not worth it.

With my Thanos reward crystals, I got new Vison and Daredevil.  That took my 4* tally to 7 with a duped Storm.  14 teams of 4*+3* or easily about +180k per arena round.  Even then, I do not think 4* arena is my thing with 3.2mil cutoff - the best I could do is probably around 1.5mil without unit recharge.  I am not spending my units for that 3.2mil cutoff though.  Just collecting premium hero crystals through milestones and saving units for 4* offer.

Currently ranking up my 4* Rocket Raccoon - a glass cannon offense powerhouse.  Mainly to be used in story quest for fast farming.  Next on the line is DD.  Got more than enough cat 1 alpha.  Also seriously considering going for Tier 4 basic cat.

New alliance quest is coming, maybe more alliances will join the fun.  Let me tell you it is fun, my advise is be patient.  It is not like story quest hit-hit-hit or arena block-hit-evade thingy.  You gotta time your evade & attacks, and draw the L1 or L2 specials.  If you got that to pat then the alliance quest is fun.

Anybody got the Ant Man?  I don't even try  ...

... what is your purpose of playing mobile game? Might having fun be one of them. If you are not having fun, then might as well take up on @Carago's offer.

Since you do play, I suggest you set up your target and go with it. If you hate grinding, why do it? Just play the daily quest for instance, you could get cats & gold for ranking up, and xp for levelling. Quest crystal offers 5 units sometimes. The daily crystal could give you a 3* maybe in a month or two, if at all. But do not expect much if you play that way, or do you want kabam to give you everything then only you would say what a great game this is?

I play to see how far I could go, and so far I have not hit a wall yet...
