My best mate is a WoW fanboy and has been for 6 years.
We convinced him to preorder ToR, he started playing at the weekend and hasn't stopped talking about it since, he loves it, to the point where he's cancelled his WoW sub.
I loved WoW, I loved the gameplay, the lore, everything. Then I got bored.
The things that make an MMO great are not arenas or LFG tools, it's community and the WoW community is dying.
I don't want to spam the same 2/3 heroics all day for points/badgers and gear score points with people I don't know, will never see again and honesty never care about. I want to play with friends, have a laugh and create memories as good as my TBC ones.
To the OP: WoW was broken as hell on release and is clearly not "working as intended" right now.
