I get where it is you’re coming from, I play healer, dps, and tank, so I know what it’s like from all angles. Just take into consideration that if you have a solo healer, they might just miss you a few times. But we can see your health bar, we know when you need healing.
The only time I use that voice line is if we’re competing a point and it’d be bad for me to dash off and get a health pack, and even then, only if it’s been a long few moments of me nearly dead and still no heals.
