I'm unsure if it's just me, but as someone who has played Sevagoth since he came out, putting a lot of time and resources into this edgy frame and standing proudly as my most used frame in the game; I find that every other ability he has is great except for his Exalted Shadow; which I almost never use and it saddens me because it just feels like a waste of time to transform into. I mean, even with the new augment, this form is practically useless and just feels tedious just to fill up the death well, transform, cast Death's Harvest, reunite with the main form, then cast reap.
And that's why I firmly believe that Sevagoth, specifically his shadow needs a rework. The shadow should be something to anticipate putting time into, because as cool as it was in the beginning, there is almost no reason to jump into this form; so I came up with some ideas:
1. Have the Shadow function as a separate unit that can fight alongside Sevagoth, sort of like Wukong's Celestial Twin or Excalibur Umbra when in operator/drifter form; and if you wish, you can jump into the Shadow form via Transference if you want more control of it. I would find this to be helpful if you want to use his augment more effectively, because the Shadow could automatically cast Death's Harvest and you can follow suit with Reap.
2. This could be a bit too OP but just bear with me: Remove the Exalted Shadow ability entirely and just rely on filling the Death Well for the passive, and if you unfortunately die and go into the Shadow form, you are forced to fill up a "Life" Well before the Death Well drains completely or you get downed in that form too.
3. I think #2 could allow room for another ability for the 4th slot that could utilize the Death Well, like the previous idea having an NPC unit that you have the option of possessing instead of a form that does nothing for you, a death ray that can inflict massive damage but drains the well faster, or another, less effective nuke that instantly kills everything within the ability range and completely drains the Well the second its cast and you must wait for the Well to repair itself, leaving you vulnerable and unable to hop into the Shadow form if you get downed.
4. The Shadow form should have some ranged abilities that don't just rely on being up close, like his claws should do what Excalibur's Exalted Blade does and hurl "beams" across the room, like tears through reality that cut through enemies from a distance, and if we could work with the previous ideas, the Shadow's Reunite can be replaced as well, maybe with an ability similar to Ash's Blade Storm, targeting a bunch of enemies that get consumed in darkness and refill the Death Well so the Shadow can fight longer
5. The Shadow can have another well to fill and when reunited boosts Sevagoth's stats tenfold, giving the Shadow some level of purpose than just being a slightly stronger operator to use when retreating.
I feel if ideas like this can be spread around we can see Sevagoth's Shadow a lot more frequently being utilized a lot more effectively, because right now its something that has no use. I mean if I could just give the Shadow a subsumable ability I could see a lot more use out of him.
I only ask for all to be respectful in the replies, these are just ideas I have been having as of late and I would like to see some improvements on Sevagoth alongside other Warframes.
