Even with the 2 map ban advantage, it's tough for nrg
nrg are undoubtedly better on abyss (though fnc could fix a lot of things), while fnc (in my opinion) are better on Haven (beat drx twice, nrg got demolished by drx, they have same comp + playstyle so it really means that fnc are just better on the comp), Lotus (nrg aren't even that good on the map idk why people think the odin is being abused there brawk is NOT dropping good games with that gun in this event on lotus), Corrode (demolished DRX, while nrg barely got it done), Sunset (fnc looked decent on it while nrg perma-bans it), Bind (nrg hasn't looked good on it, fnc is just good on it)
Ascent is a coin flip
Personally I think fnc completely botched the map ban, why ban corrode if they look this good on it?
So NRG Ban Haven, Sunset
then FNC pick Corrode
NRG pick Abyss
FNC pick Bind
NRG pick Ascent
Lotus remains so FNC win either 3-1 or 3-2 (since they're better on 5 maps, nrg can only ban 2 of them)
