100% theyd beat gambit but something i dont see enough people realize is that both gambit and sen would be in the top 10 of teams in the current landscape of the game. I mean there are so many teams that wouldnt even be able to compete with them like TL, FPX, Kru (...maybe), and theres 1 more im forgetting.
Those 2 teams were the KINGS of fundamental game and simple plans and strats. They never overcomplicated shit and were able to always be really consistently good. Thats why FNC are dominating rn. Its not like they have PRX level set plays, or FNS and Saadhak level counters, but by playing the fundamental game to perfection youre already better than 90% of teams that are tier 1.
