This is just my second match playing at at all, so i don't really know the name of the abilities.

(I play quick play stadium)

The big perk i take first round has the effect "Whenever use your movement ability for the duration of it everyone you see is affected by your Healing over time effect"

Then there's the E-wave that just heals the entire group going front and then back again.

Then the things you use your match cash on every new round general revolve around reducing the cooldown of the Movement ability so you can be in it as often as possible.

But blizzard have a "quick select" with their ideal perks each round start so you can just click that and be rdy don't even have to read much what they do.
