This is how i see it..
Magnb
pros; more group utility, possibly a little more easy to play, overall more creativity with the abilities and options
cons; a "weaker" version of a magsorc (not sure if true) overall lacking dps compared to other mag builds
stamsorc
pros; great single and aoe dmg..that's all i can think of really..lol
cons; boring in terms of abilities as most stam builds have the same set up..
Why do you play magnb/stamsorc in pve?
