I just looked at your build Magicme on d3planner. Looks fine and a like you said everyone will have a different idea of what skills to run. I caution you agains't Elemental exposure though. It doesn't seem to stack. By that I mean, 4 Wizards using it with 4 elements each doesn't lead to an 80% damage buff like almost every skill for the WD does. Even with 4 running it the highest you can get is 20% damage.

The effect does work for the party it just doesn't stack from multiple wizards. Not sure why that is the case for EE when for WD pretty much every damage buff they have but BBV stacks. I've tested the new cold zdogs, piranhas, posion haunt rune and mass confusion and they all stack. The only one I haven't tested yet is Hex but I have a feeling it will work too (as long as multiple shamans can all hex the same target... not sure one this one).

I also tried testing Cold Blooded passive and it doesn't seem to work either. It seems to increase all the damage the wizard him/herself does, but doesn't seem to work across the party properly. Wizard got kinda of short changed on their group buffing potential compared to other classes. WD seems to be the king of damage multipliers atm, Crusader has a nice dmg buff + a large crit boost and can spawn globes, Barb has movespeed buffs and Ignore Pain that can work for the party and can also be a globe machine., and Monk has Forbidden palace and the physical rune on EP that buff damage and palace also offers mitigation (even if it is a small area). Wizard really seems left behind in the group support roll heh kinda like the DH..
