This is top on my wishlist. Personally I would rather this be done before any changes to any powers that would make me want to do a respec. The respec system was good enough before IOs I guess. But with IOs, it's simply terrible and a horrific user experience.
Clearly admins and mods winning days shouldn't be allowed, it's basically insider trading and various RICO violations rolled into one. I have no particular reason or motivation for saying that and certainly wouldn't have anything to gain at all if my most excellent idea were implemented immediately.
I've only made this combo on a Scrapper, but those are the Incarnates I chose, and will choose again when I make this combo as a Stalker. If not Reactive, I like Degenerative too.
I'm already throwing around ideas for MunkiLord's respec.
That's a good start, you'll be able to get that quite a bit lower if you can keep Soul Drain and AAO saturated. Though Dark Consumption doing so much damage may actually be a hindrance in this context now because it'll kill off some of the SD/AAO fuel.
They're as useful as most Tanks. If someone wants to rock the aura and spam heal, I don't care if the team isn't struggling. If we're mowing through mobs, they can go invisible and do nothing but use dance emotes in the middle of mobs as far as I'm concerned.
