To the people who think healers won't be the most essential foundation of groups in this mode(as they have been in both iterations we have gotten of pvp so far) - have you not been pvping at all in this game?
If you are 2v2 and you have 2 dps/tank and the other has 1 dps/tank and 1 healer the group with the healer will win guaranteed... this applies to any group size ofc
This is, of course, unless they are making some severe balance changes which probably won't happen.
