Agreed. You buff them once and be on your merry way at least that is how it should be. About HUD's we don't have an concrete info on that yet. Should buffs have a time limit or just till you die?
Someone where I read that a buff will keep one of your PIP's used up i think it should have a time limit or death, whichever is first. Or perhaps you can choose to remove a buff from someone? However, if it turns out that a PIP isnt used then it should be a time limit for balancing issues.
To clarify, which death do you mean? The Buffers death or the person being buffed death? To me, it would make since that if its like a shot that your giving them than it should be only if they die, but if its tied to your PIPS then its both.
