Convection Vs Concussion

[Mag]

Hy everybody.
First of all i'm sorry for my bad english. I'll try to be clear.
About the 7-2-32 spec I always had doubts if is better pick 2/2 Convection or 2/3 Concussion.
Atm im going for Concussion for some reason:
1: work better where there are some dmg modifier (magmaw for example )
2: Increase benefit with better gear
3: More dmg (kills with only 2-3 people alive happen =D) - (ohhh crap 0,2% wipe, if i had concussion!!!)

i dont think there is a lot of difference between this 2 talent, but, what u think?

Greetings

Well "normally" convection end up coming out as better choice for pure regen. Concussion can be better if the fight has high % dmg modifiers

basically it all comes down to if 4% more dmg is more mana then 10% less mana cost on lightning bolt (140mana).
