Until I get the rupees to get acces to the server, I was wondering if some abilities work unlike on other servers. These are the ones:
Rogue-Vanish/Poisons/Blind/Distract
Warlock-Enslave Demon/Use the soulstone
Hunter-Tame pet (do pets work like on blizz with happiness or are minions?)
Warrior-when does the rage regenerate?

Plz answer because I look forward to playing on this server

i can answer you the warrior part: rage generates when you hit something, based on the damage you do compared to your lvl. i dunno if you gain rage by getting hit cause theres sooooo much time i dont get hit at all

the quest for the hunter pet is working and yes you can tame pet.

I don't think poisons work though I may be wrong since I'm still lowbie on my rogue.

I use this post to ask one more question: warrior stance, in particular defensive and berserk stance, r working? Cause in most private server the quests to take them are bugged...

For the alliance, quests are working to get stances, I dont know for the horde but its should also work.

To add to the previous response about rage generation--rage is generated when damage is received, but once your defense gets starts approaching 1000, you won't see much damaged-received rage.

edit: That is, generated when you deal AND receive damage, but the latter becomes rare once you hit 255.

i was dueling with some other players and finally i got hit in a long time, so i am 100% positive that rage is also generated when you get hit.
so rage is generated when:
you hit something (the more damege you do ocmpared to your level the more rage you generate - a lvl 1 dealing 100 damage will almost fill up his rage bar, while a lvl 255 dealing 100 damege will barely get 5 points)
when you take damage, dunno if its scaled acording to your,or your enemy, lvl.

Yes, works for horde too
