Well I hope they will work together well enough to make this class feel different from the rest.
I mean since nothing seems to have been made to works together in this game, you just use the strongest skill available. Well for PvE at least.
So every single magicka DPS Wall of element, inner light and only a very few do not use elemental weapon.
Since barely anything synergize together, the only reason to use a skill is because it simply has higher numbers. (be it raw dmg number or raw buff %). So making a class that would have enough skill powerfull enough to outshine every single weapon/guild skill would just be OP. giving them the same power would just be a re-skin.
But Necro have something different. They have skill that benefit from each others. Skill that provide corps and skill that use corps. I do really hope that ZOS can find a balance that will allow us to use many of these class skill.
So my magicka Necro would feel different from my other magicka damage dealer. Cuz weaving elemental weapon is getting old.
