The MK2's Hybridized Shot is a bit too good.
Maybe have it take a Quick Action to activate and work for the whole mount.
Otherwise, I do like the MK2, even with the reduced system points.
It's been a while since I played the original. I recall the wall effects like like Conflagration or Wall of Force doing damage over time to anyone standing in the area, PC or NPC, but that doesn't seem to affect NPCs in this version, only PCs. Is that supposed to work like that?
Also, are the weights and carry capacity still the same? It feels like characters are getting overburdened a lot easier even with just a basic equipment load out.
