First of all, I am excited about these changes!! The stat increase helps greatly with Saryn's survivability and squad placement as a 'mage-fighter.' A few things I am concerned of what would happen though.
The current 'Max-range Spore Saryn' has the bonus of spreading a lot of spores over a large range but did have scaling problems against 'end-game' level armour. The current revision presents problems I can foresee. Enemy density will be a huge factor in how bad (or too good) this turns out to be. For example, Sanctuary onslaught would not require recasting at all through each wave but spreading spores may be a problem on some tilesets, notably the huge Corpus Ice defense tileset. Such missions might render Spores useless, while Hydron might solidify Saryn as meta for certain missions with high enemy density. I am also concerned as to whether Spores will still spread toxin procs as well, as it has been a problem in the past? Also, having the damage ticks/sec beign positively affected by duration would be hepful, but may be OP due to the nature of corrosive procs.
As for Molt, I am content at the moment with the changes, as long as the proc shedding and regenerative augment is not changed. One thing that I may be too hopeful for is the decoy to actually draw enemy attention more (have had the decoy completely ignored once).
Again, same for Toxic Lash, I am content with the changes for now, but I don't see the augment being used anytime soon, as we can put gas damage on weapons for the same effect. The removal of energy gain does not bother me, as there are other ways of gaining energy and Spores, which will be changed, was the main energy intensive ability. I do use Molt a lot for the augment, and does require a lot recasting on my part in sticky situations, leading to some energy problems. This is the only part of the kit I am concerned with over energy problems.
Miasma is a problematic ability. Parts of me agree with bringing back a more nuke-type skillset back for Miasma. But due to the damage type, I would actually prefer a more CC oriented ability. I would prefer to have a viral effect spread out over a large area, one of the pros of Spores before this revision, but a higher range would need a lower damage output. Because of this I also would like Spores to be able to carry Viral procs too, if Miasma will be the same as the revision. This revision of Miasma seems like a hybrid of pre-revision Spores and a nuke Miasma. I would prefer a more CC + proc oriented Miasma.
All in all, I am still looking forward to a revision of my favourite poisonous lady!!
