1) Yes and yes. You can even do crouch throws, both of them, out of the armor dash.
2) Yes, 236A+G
3) 44A feels nerfed to me too. But I think he'll be more effective at zoning than in SC5 because JG is gone.
Actually I think WL A does give you a lethal hit if you aGI something with it, that's the condition for this move to Lethal Hit. IRM or PW shall confirm this.
WL does not beat 2A, but it does beat every verticals including kicks. PSL1/2 aGI beat 2A clean and can guarantee some stuff like RC A B, so it's pretty strong !
I think SC5 44B is now 3B, it's even better ! But the thing I liked the most here is the 33bA from SC4, hit high with a good RC transition... I loved that move in SC4. With how fast and tech crouch RC K is now, that's even better !
