Hey friend, thanks for replying. Meant to continue the discussion earlier but life interrupts. Anyway:
I agree wholeheartedly.
Here's the thing though: his stats are good enough that you can do a lot with him even with a small investment. Currently, I have in him 1 diamond key and just enough cash to unlock SA1 and the first stage of SA2, and an extra move slot. With just that and a valentine, I've been able to clear streak 20-29 easily enough for the last pfs. To get the same performance from my other diamonds with better SAs but worse stats, I've definitely had to invest more than that. The bottom-line is that if I had known to use him more when I first got him at level 20ish - and not have been discouraged by all the negative reviews - I'd have struggled less then, and be further along now.
I might suddenly find myself in the minority here, but I've never thought of him as a defensive variant, precisely because, as you say, he's bad at it.
Not sure what you mean, but as of update 3.4.2 (right?), his SA2 can activate at <50% health; no need for teammates to die. I've managed to trigger it while my whole team was still alive (and unharmed even). I find that regen or, even better, final stand from a valentine or whoever is usually enough to keep him on his feet.
For his SA1, you're right, its still inefficient. But I find that its not something you trigger on purpose anyway. It's more like an emergency measure, like a parachute or something: unnecessary when things are going well, but really great to have when things are going poorly.
For the last PFs, I've been putting him as the first fighter, and a valentine, usually a Killjoy as third. If things go well, this is usually enough to defeat opponent 1 and 2, and greet opponent 3 with a BB3 for a chance at insta-kill. If I mess up and get the whole team killed, Killjoy resurrects him at 100% damage, which is a LOT, certainly enough for a chance at a comeback.
