since its going to wipe off... so lets group up and explore some dangerous places lol

Then you obviously have not played much MMO . Exactly which part of this game is 'WOW CLONE ' ? 
The only way for them to improve in order to meet today's standard is to rebuilding the entire game from scraps.
The other MMO have progressed way too far , even the other Korean MMO . Try looking at notorious Blade&Soul and come back into this .
This game is 6 years too late for release , the sequel system and exp grinding is way too old for everything (OR anything ) to happen.
I had my first impression on the game , now that makes me wonder exactly which part of this game is worth that 3.8 GB .
Its all the nostalgia people had for RO 1  , moving onto RO 2 with all these hypes just to find out its disappointing .

The server issue was a mess but since its a close beta and have playtime limit I will skip the details here.
I am running this game on 3770k and 680 Sli , but this game is working very poorly with my PC. (with 64 bit OS )
I turned on the shadow and distance to the max and the game is barely running at 15-25 FPS . 
The game also look very uninspiring , the cartoonish spell effect is a big turn off .  Every spell just look like a palette swap version of each others.
Building and all the polygons looks jaggy , the background of the scenery looks like its a 10 years old game.
I played a Magician and every spell looked the same for me. Such an awful impression.

The only thing that look decent is the character models and the vast selection from hair style and facial customization that resembles RO 1.

Movement control system is also sluggish . Feel like I am rolling on a random snowball that randomly push you to different directions.
They have also assigned several GM ingame to answer questions.
But I found a gm standing in the middle of the starting poring field , its downright distracting .
Instead of actually helping and answering questions , He transform into Bears walking around  as if he is bragging with all the level 50 items he has . Very unprofessional.
Overall , this game is not a WOW clone . While WOW is often considered outdated in graphics but they are still looking much better than this.

p.s. : Not recommended if you are 8 years old or above  . If you really like RO, go back to RO 1.
