I think the arcade boss version of the Seth has slightly different properties than the player version you can select in versus mode. He can't use specials until round 2, has more health, and I imagine some better numbers on his moves. Generally I find the AI in Super and beyond a bit too 'psychic' for my liking. It's not even subtle about reading your inputs: Be neutral for ~3 seconds, press st.mp halfway across the screen, cpu goes into ultra before you even change animation...

Oh yeah, I'm trying to play Marvel versus Capcom 3 now, since I've fallen out with BlazBlue since its own arcade rebalance. Only playing offline casuals though as I don't like the online. 8-man lobbies, no spectator mode, :trollface:
