When you play Phoenix it can get incredibly frustrating when nobody on your team stays within your radius long enough/at the same time - it’s very difficult to heal multiple friendlies at once (unless the team is communicating well, which isn’t always the case).
How about we introduce a ‘call out’ for Phoenix so that as soon as he starts charging his pulse, he says something like “come and get your health!” so that nearby damaged friendlies can know to come a bit closer so that they can all get healed by the pulse.
This would, in my opinion, make Phoenix a lot more viable in non-competitive games (where there is little to no communication) while not at all making him too good for balance in competitive games (as it does not effect his actual abilities at all).
