To have higher win probability sen should improve their map pool even more.
Sens lotus, split and sunset are very good.
Bind with geeko comp is also good.
Their icebox isn't too worst unlike their breeze or ascent.
Sen doesn't even have a damn clue on what's going on around in breeze. May be playing un orthodox comps can fix that like tenz your. Same with ascent there are not getting proper info causing late rotations and blunders.
