I do agree with a lot of what you are saying here. I also like the idea of flipping the AoE with the Totems. But, there are some issues with what you suggest.
Forsakers losing Chaos Totem may make it tough for the class to ever hope to pull off any great crowd control.
If Mystics are supposed to have a more Supportive role, then they should not be pulling off great crowd control using Chaos Totem.
For Mystics Losing Fire Rain and Hellfire but gaining Fire Totem would probably not ruin the class, though it would be weaker. I think when people say Mystic is OP, I only agree in a Player versus Monster context. Yes, if you want to grind for Exp on massive hordes of beasties you find a Mystic and get yourself a mount and just go rustle them up over and over. That sounds like fun to me. In Player versus Player, I find on my Mystic, Hellfire and Fire Rain are only really so overpowered when a bunch of mindless NPC are jumping into the inferno. Players, well, they tend to walk around.
Thank you for your response.
I do agree with your aspect. Chaos totem would be too OP at mystic skill bar.
Let me revise my suggestion.
Mystic would get the Fire totem and Plague charm/ or make Fire guard special mystic skill with tripled amount of rez (on lvl 10=30% rez). These changes would open more supportive view of angle to them.
Forsaker suggestion remains, without loosing chaos totem.
I was thinking about to make a comparison to templar classes. Mystic should play a supportive role like Radiant ofc on a lower level. Forsaker in my opinion has lot of similarities to the Tempest. Both have magic mastery, magic weapon mastery, AOE (atm 3x for Tempest, 1x for Forsaker). Crowd control represented by Sleep (Radi also can have it, but its okay since Radiant does not have such a dmg output as a mystic), and Chaos totem.
Hopefully you consider some of this reworked suggestion about bringing balance to shamans.
Thank you in advance.
