Here are my first thoughts on Occulus:
Chain lightning is sweet.
Blast Off is also sweet.
What the heck do the poke-balls do? Can I catch-em-all? Put them on my Christmas tree? They only seem good at level 15.
Brain Storm does not remove negative effects as it is supposed to. When it does, I think Reg will have received another nerf. Will also remove stuns?
I'm not sure about the passive abilities. At max rank, the lightning aura provides a 10% chance to deal 100 damage. The expected value of that is 10 more damage each hit. Ten DPS is nothing for three whole skill points.\
No stuns or interrupts automatically put him on the Tier 2 list, in my opinion.
Any thoughts?
