I don't really care about AH.
My concern is always the builds. And the synergy of skills.
For me, builds and the synergy of skills make D3 interesting.

Nerf on skills has virtually killed 90% builds.
AFAIK, monk and witch doctor are not as badly affected as other class.

Nerf on gears, i.e. LS weapon, IAS gears, change many builds and gameplay too.

Killing AH is making it worse, indirectly killing more builds.
i.e. C4 dog for WD. Chakram build for DH.

I would like to give the benefits of doubts to Blizz.
I hope I can find the similar synergy of skills in RoS.
For now, patch 2.0, synergy of skill and builds are rather disappointing.

Those play everyday know very well that AH is not an issue to begin with.
Seasoned players know very well the problem is the loots or the drop rate of good loots.

Those complained about AH are those seldom play (or never play?).

Gold is VERY important now, especially we're doing a lot of crafting.

I just spent few hundred thousands of gold on craftings last night.
What I got was far from godly.
Perhaps I need to spend few hundred thousands or millions more.

Go for GF instead of MF.
I find GF gives me a lot of gold.

Use the gold to craft items.

Crafting is better than loots, generally.
Many of current 2.0 legendary gears are worse than 1.0 legendary gears (i.e. skorn, EF, mempo etc etc etc).

I reckon only lvl70 loots will replace our current gears.

Zuni's set.
1.0 - it generates 20 mana per sec
2.0 - it generates 7 mana per sec.

Without high mana generation, you will have problem spamming bears.
Blizz killed bears build if you use new Zuni's set.
IMO, new Zuni's set sucks balls.

Loots are not really better. There are way too many suck-balls legs.

Crafted gears are better due to high base stats and VIT.
But that doesn't compensate the loss of killing builds for all class of chars.

Synergy of skills and resource generation are pathetic.

Current legendary set's bonus should be the same in both D3 2.0 and ROS.
