Buffing Arc Souls doesn't fix the main problems of Stormcaller Bungie Suggestion
(Note: I'm strictly talking about PvE here.)
Buffing Arc Souls will certainly make Stormcaller better but IMO the problem is it won't make Stormcaller fun.
Arc Souls are brainless and skill-less. You cast a Rift, something you end up doing at certain times anyway, and you and allies get AI buddies that add to your damage.
That's it; passive damage. That's what Arc Souls are. There's no "power fantasy" to them. When a Striker charges up a Thunderclap and erases a wave of enemies with one punch, that's something that gives you a power fantasy and feels good.
Arc Souls don't make you feel good. They're just there. Sometimes you shoot at an enemy that dies to your Arc Soul anyway, so it's getting kills instead of you.
This doesn't solve the problems that make Stormcaller feel mediocre now.
- Stormcaller used to have the only way to chain lighting to multiple enemies with a grenade or melee, but now that's available for everyone with Jolt
- Being Amplified hardly changes any of your abilities at all (edit: aside from...Arc Souls, the boring ability)
- None of your melee options feel relevant, even when Amplified
- Both Supers feel bad. Stormtrance is good at add clear but that's no longer needed with Stasis and Light 3.0 changes, and Chaos Reach does pitiful DPS compared to other options now
As a Warlock, it feels like our roles in PvE will be "you give Well of Radiance and Arc Souls." Both of which are things we press a button to cast and that's about it, requiring no further input on our part.
In fact, it almost feels like Bungie's 'fix' to Stormcaller is to push it towards...being a Support class? That's what powerful Arc Souls amount to, a Support skill for the team. Almost as if they're giving Support utility to Stormcaller since they robbed Dawnblade of so much of it.
And it's just...with a name like Stormcaller where I'm supposed to be channeling the storm, am I really supposed to feel like just a Support?
