I play both casters and melee and I must say there is a very big differenece that is hardly never mentioned.
As mage / healer there is always mana issues when playing minigames. ( drained by enemies, pool to small for too high mana cost on many spells / heals / abilities etc. )
When playing melee there is NEVER an issue with stamina.
I think its ok that people have to be aware of how they use mana and stuff, but this should work both ways.
Its not ok for melee to be able to dish out combo after combo and abilities and never run out of stamina.
I see all the time people writing " I was out of mana, sorry" etc. But I have never seen or heard anyone write or say " I was out of stamina"
This is a flaw in the game and should be changed.
