Class with most control

I got 3 questions, so that i can pick what to reroll:

-which classes in your opinion offer most control in BGs. for example making 5 enemies useless for a few seconds every now and then.

-can survive having <1000 resilience and still support their team.

-can selfheal if needed

-are good enough for 2.2k rating in 3v3 or 5v5 without needing craploads of pve gear
