multiple roles btw classes isnt going to happen , Yoshi has said no and no again to this ....however i think being able to choose 60-70 traits or something like that wouldnt be an issue , yeah u will have a spec for raiding a spec for soloing and even spec for AoE or Single... but at least u will feel "different"

fire V: does massive dmg to single target 600 potency, or does massive dmg on aoe 250 potency, or puts a dot 800 potency

swiftcast: makes the next 2 spells instant , makes u able to move while casting , or makes just 1 spell instant but boost dmg by 20%

Adloquium: crit chance +15% , adloquium crits power multplier x1.5 , adloquium no longer heals but the barrier is boosted by 75%

Trick attack : duration +10 , no need for suiton effect , cd reduction of 15s

random examples , with no balance in mind at all :P
