Ok so i levelled my alt demo warlock to 100 and build a barn lvl 3 for the fur and the blood, by doing the elite wolfs in nagrand i noticed that all the tanking pets voidlord and infernal (with demo servitude) are being destroyed in 2 hit, the wolfs leave them to 20% health after the first 2 attack and by the time it reach 50% for the trap i've already been forced to resummon it 2 times; my gear is ilvl 630 i've tried putting the demonic training glyph etc.
Is there some kind of bug with those pets or have blizzard nerfed them what is going on?
