>support abilities, healing?
the healing is locked behind perks in the perk tree. bulwark has an active heal, when you drop you flag you and anyone about 10 feet near you restores all contested hp. in this case they need to know to do damage to heal. and vanguard has a perk where you passively heal when you execute an extremis enemy, but this is only really good on the highest difficulties that spawn lots of high level enemies to heal off of. the most over powered weapon in the game is heavy's plasma, and then the power fist. but just use what ever you think looks cool or you like to use, you can do well with any weapon.
