Balance, economics, stability.

Hello,
I have played tbc on privates before, played atleast half a year on molten's cata, 2 years MoP on molten/warmane. Have played live legion, but since I am predominatly hunter player was disappointed in boring gameplay on live, long loading screens and playing mw monk (I do play healers as alts) 24/7 didn't cut it for me either. Looking at warmane again, seeing MoP is past now, wanted to ask about current state of tbc here and outland server.
1. What is the uptime of server/ how often you guys get kicked out of the game/queue and such for non donating players?
2. How is leveling/questing? How many of instances/raids work? Is questing bearable? How is world pvp while leveling?
3. How is balance in PvE and PvP? What is the dominant classes/specs in healing/dps?
Thanks in advance.

Also, auction house - is it working as it should or is it inflated over the roof?

1. Pretty much 24/7 without interuptions aside from scheduled maintainence, which is less often than retail servers.

2. Most quests work (by most I mean you can level and not find a broken quest, I found more broken quests in max level zones, a lot of those have been fixed since launch too), most dungeons work tho low level ones sometimes have minor pathing issues, some bosses occasionally don't drop loot, not an issue in max level dungeons, for the most part they are very decent with good scripting once you hit Outland, but for sure not perfect. World pvp only consists of you getting ganked by higher levels or groups of players, or you doing the same to others. World PVP is rarely a mutual thing anyway.

3. Balance is good, pretty close to retail.. There are minor bugs across the board but there is nothing major, it's very good in general. Nothing really changes from retail in this regard, differences are small margins.. Threat generation for Bears/Warriors seems tough, but may be due to the general playerbase playing like it's WOTLK.

4. AH is fine, actually the issue is a lack of herb/mining spawns and droprate on blues/greens, droprate on motes... It means they are overpriced due to high demand and low supply. There is not enough supply to meet the demand on a lot of stuff currently, plenty of threads about it so hopefully something is done.
