So, playing around with several of my 60s now, and re-gearing, re-blessing, etc - Scarlet Witch is pretty unstoppably beast-mode (again). She was before, so no big surprise, but now she is my character that feels as much like pre-patch ass-kicking as possible, where as most of the others feel slower and squishier. Going with a -spirit cost reduction build out, so that I can have 100% uptime on Chaos Overload, which makes her incredibly strong and destroys things. Anything non-boss flagged is just destroyed instantly and bosses melt decently quickly enough. Can handle all cosmic content again just like before - I do die a bit more often than before if I'm not paying attention, so it's not as brainless as before.
Lot of their decisions are still stupid and poorly thought out, but glad that I have at least one character who feels epic still. So many of them feel so slow and weak now, it's sad.
Can't really say I recommend it to a new comer at the moment, or anyone really who doesn't already have a lot of good artifacts and gear stockpiled. Also, the leveling experience is comically easy. Been leveling all of the characters I'd gotten through bogo or whatevers and they tend to hit 60 by chapter 6, quicker if I use any exp boosts. Don't even usually have much if any gear on them by the time they hit 60 either, maybe a few epics.
