I like your description of the Shade. I do think those are a lot of the things that really makes her shine as a career(especially in melee). She doesn’t feel overpowered or underpowered, but she feels very versatile and like you can make a lot of power plays with her the better you are. She doesn’t feel that reliant on any one set up. A number of her talents are good and her passives are pretty good. They seem to have her in a pretty sweet spot at the moment.
I’ve played around with WHC for a while and could never really get into him. His passives and talents are so reliant on too many RNG factors. When they work, they’re satisfying; the lack of consistency makes them feeling less than good though. He feels a bit pidgeon-holed into specific set ups. His active feels really lack-luster. He feels like he’s almost where he needs to be, but needs a few tweaks to really get him to that sweet spot.
His talents could use a little “livening up”. Specifically his 15 and 25 tiers. The 2 temporary life for Justice’s Bounty could probably go for being either permanent life or a quantity higher than 2. Maybe 3 or 4 and see how that works out. Marked for Death’s attack speed boost doesn’t feel good because it only occurs after the taggable enemy dies and for 4 seconds. Either a longer duration or having the buff proc every time Victor hits the target would feel much better(especially the latter). The same concept applies to Wild Fervour as well. For Justice’s Bounty you might be able to do the previously mentioned suggestion for the talent, or make it so every time Victor attacks a taggable/tagged enemy, his team gets 2 temporary health. Just ideas.
For his 25, adding something with a little more flavor would be nice. None of the choices feel that great other than the CDR(but that’s only because the CD is massive). Adding a bonus +15% attack speed, movement speed, or something else would be great instead of some of the current options. Or make it so a 25 talent applies the Witch-Hunt bonus damage to all enemies hit by the active. The duration of his active in general feels too short to be really useful. Just stuff to throw out there.
