I play it quite a bit - just not a lot to discuss I suppose any more than we see MOBA discussion. My favorite characters right now are Dynamo, Venator, Doorman. Danny is probably after that, although for sure he's getting a nerf when they do a rebalance of all the new guys. In terms of the new characters:
1) Harrow's kit is odd - her 3 standard skills are ok (although her #2 is all but requires you overheal the characters it is used on or they might die), but her ult is insanely powerful. Especially at max rank - she's literally invuln to damage while ulting. She isn't immune to CC, though. But you have so little time to react that the only CC that works is if you are behind her or it is a super long range CC. Her ult is 100% getting a nerf. But if they nerf her ult, they need to give her some more offensive utility. In team fights, especially early, you can't really contribute much to a fight, but by late game you practically become a carry with your ult.
2) Violet is extremely powerful - her portrait skill has a really long range and in practice is extremely hard to avoid and her ult is extremely powerful (her ult is one of the few things that reliably counters Harrow's ult because the paint blocks it). I suspect she will get some nerfs
3) Danny is really fun to play as and frustrating as fuck to play against for the same reason: his airtime in his jetpack. If anything gets nerfed, it will probably be his jetpack/overheat dive #2
4) Solomon is one of those really high skill ceiling characters - if you can micromanage moving his chess pieces during a fight, he is extremely powerful because you can't destroy his chess pieces and some well placed bishops can do a shitload of damage and stuns. If he was to get some nerfs, it would probably be to the bishops
5) Baba doesn't seem too bad, except her goomba stomp spam that heals her. She can do that WAY too often, if anything gets nerfed it will probably be that
