I am a light Medic. You have to let them know when you're out of pips. But another suggestion is to not buff as often. Rather, focus on saving pips for revives when you get to choke points. Since you're a Medic, I'd also like your opinion on something too. I have all the Medic abilities including Lazerous. The only one I regret getting is Share Supplies. Do you have Share Supplies and is it worth having as a Medic in your opinion? Like I said: Its the only one I regret getting.
If you have the double boost, it is worth being generous with that buff. That's anywhere from +45-+25 health (depending on how many boosts they already have, starts at +30, gets 5 lower per additional boost.) If you are refilling a damaged player, it could easily be +80 health, the boosts don't refill without a medic's help. Plus if you can save a red health guy in combat with a boost, it is better than a revive. It is a tricky resource management game where you have to make a ton of judgement calls.
I have to agree that transfer supplies would be far better on another class. How many supplies does it transfer? If it doesn't use them all I can see it being good where one medic is empty and the other medic is at half. It is better to have 2 medics with supplies than one empty so you can cross revive if needed.
