The truth is that no one was more powerful than human WoTLK Gold. I'm not a fan of saying that because I'm not an avid fan of gnomes. Sorry, that's just what I am.
But no um does give more DPS and a human niche provides a thorough breakdown on the mage discord , pinned to the wrath of the Lich King PvE channel. I'll also publish it on my Discord channel and give credit to him. It breaks down into your seventh gear, and ending game gear changes the DPS difference between gnome and human or at least not necessarily DPS difference but the stat differences. It is evident that gnomes are going to have more crit , as well as some extra damage to spells through the mind mastery skill over humans.
And while human has every man for himself that PvP trinket, which is part of the race show allows him to gain access out of any OS of CC majors can use iceblocks as well as a blank that can be taken out of stones. We don't usually require that. Therefore, a human might buy WOW WoTLK Classic Gold get a bit better when it comes to situations when he needs to clear his mind of several CC's.
