As a rebel, I feel I can be neutral on this issue.
If you're squad is struggling in the current state of the game (and you would not be alone in this), I do suggest you join forces with another squad.
Squad's make the game. If you have offers from L50 squads you can only improve your lot. High level perks can be very helpful. Advice and replays from high level commanders can only help you improve as a commander.
But you must do what you think is right, of course.
