Nah for real, round 1 is an utter slaughterfest in favour of team 2.
Round 2... well to be honest Grievous and Jaden are fodder because of the titanic Force power they're up against. From there team 1 is still inferior and outnumbered, so it's even more of a decisive win for team 2 IMO, especially considering Kun's amp.
I'm pretty sure Grievous isn't defenceless against lightning. He tanked Durge's electrified bola without issue and his armor is sufficient to tank several hits from a starship laser cannon, which are designed to crumple military fortifications. Let me know when anyone here has lightning on that level.
