I believe that the distinction is abilities with a cost that changes versus ones which don't, probably for purposes of downranking. So for example Raptor Strike has rankings though it's melee since it uses varying levels of mana. Whereas WoTLK Gold just ever reveals one rank because it's a fixed price. Well, not necessarily. Only mana cost. Rogues don't have charm rankings either. There's no reason why you'd need to down-rank on any class that does not use mana, as their costs don't go up either.That's a good question - are there some anger or energy-using skills that change cost between positions? I suppose not.
It was baffling to me how frequently people would legitimately attempt to argue that raids in vanilla shot skill, and that raids now are faceroll. Raids have mechanics today. Vanilla raid bosses, you're lucky if they have any mechanics in any way. Plenty of managers just have a debuff to manage, and you deal with it by decursing, or simply being debuffed. Wow, such mechanisms. I really don't know how so many people seemed to believe vanilla had challenging raids.
Since WOW gamers are 10x better and have 100x more information and tools (infinitely superior plugins, sims, really fantastic computers which operate WOW WoTLK Classic on more than 25fps in raids and adequate size screens, voice communication and mics made in 21st century). I'd be prepared to bet than any ordinary player who follows guides, watches few direct videos/streamers is a better raider than many"top raiders" throughout vanilla times. Seriously listen to some of the people who raided seriously during vanilla (Preach has some great stories) and you understand that even the best WOW players were just winging it like everybody else.
Mate abilities are also 1.12. Some casual guilds already awakened over BWL. AQ40 is a entirely different raid and even though my pserver encounter was harder, mechanics onto a struggle like c'thun in which you've got to all walk into the boss struggle room at the exact same time and disperse all 40 members outside so with not one person actually messing this up. If you don't it will probs wipe out the raid cause of a laser he shoots that does big dmg and chains into a person if you are close enough. It can literally string around the raid and with a fight as long as it is healers will finally show themselves in buy WoTLK Gold.
