Hmm i just played a game with a bunch of friends, and i noticed one thing :
early in the game and later they capped with all of their squad, this is a big mistake! Never cap with all of the squad, early you waste time as you could be caping two points at the same time, and later in the game, if you regroup everything (blobing) you'll get smashed by a manticore or global abilitie.
Always cap with a single squad, even if you lose it, you'll maximise your chance to preserve other squads !
This is what you can see in campaign mode, dont' repeat that in multiplayer, it will cost you dearly.
Also some squad can cap points faster than other, i'll post about that later when ive gathered enough infos !
