SEN is easily the best team, they just got extremely unlucky in LCQ.
e.g. when Shroud tried to solo plant Icebox B backsite (200IQ play) and got stuck in the washing machine due to RNG utility combos. Step bro Zellsis ran in to save his ass but died to an unlucky 1 tap from a non-moving (coward) enemy
Only logical conclusion is god hates shroud and cursed SEN
SEN should be at champs not 100Ls they would steamroll these boring ass teams that just camp angles
