Tanking is, hands down, the hardest role in a group, both technicly and in the dynamic of a group. Its not hard when compared to other things [DMC is hard, if you want a measuring tool], but in the context of the game, its the hardsest it gets. The reason is that you are basicly incharge of the group, and you have to make sure none of the stupid things the other 4 people in the group dont kill you. you are there to fix the problems the other people in the group create with their lack of basic skill.
Why easy?
Just because warriors have to press more buttons doesnt mean tanking is harder...in fact, tanking is easier because they have so many more options at their disposal.
Whats a druid to do when the boss goes beserk and attacks 30% faster and hits 50% harder? Stand there and eat it...thats what
Whats a pally to do when a super-powered pyro is coming to your face and your DPS is too retarded (or unable) to stop it? For sh!ts and giggles, the mob is stun immune
What about when your healer gets silenced and you're at 20%? All 3 can pot (druids is risky and it costs all the rage you had saved up)...but what class has other options?
Tanking is NOT just creating threat...thats just half of the grand puzzle. Tanking is also about mitigation...it's about having tricks and abilities for situations...pallies and druids COMBINED dont have as many as warriors do.
Yes...warriors have more buttons to push to do their job...why dont you stop and think for a second why this is GOOD for them instead of whining that you got more buttons to push
