Hmm, I'm not sure about this--I think it's just a different kind of learning IMHO.
How many melee do we see that have no clue how to block let alone carry a shield in case they need to block for some reason?
How many actually understand attack from behind?
How many understand that the main tank is chained and to adjust their attack?
How many understand healing amp? Or DR? Let alone the finer tactics like trip ?
How many actually back off from a mob before they have 1 hitpoint left?
When to frenzy and vicious, and when its a bad idea?
When to Madstone, and when it might be a good idea not to?
How many know how to kite? Or tank HOX with just solid fog clickies?
How many experienced Melee do we see that run around with no pots of anything to use in case things go wrong? Inexperienced Casters at least can rebuff themselves and a good amount of time heal themselves.
And to bring up everyone's favorite raid to bag on, a melee without heavy fort in part 4 or 5 of the current shroud and 300 HP will prob die, where as a caster with the same situation will prob live. . .
Ive personally met more terrible melee than casters, but perhaps I am just lucky
