Are you just looking for confirmation or a solution? If its just confirmation then than the answer is yes others feel the same (I'm looking at you
@dnd4vr ), and some do not. And that is OK. If you want a solution we can discuss that too.
Personally, I think that is a perspective issue. If you feel your character would push on, then push on. That is what heroes are made of - they keep going despite being beat-up, fatigued, and not at their best. I find it more immersion breaking to be able to do the same thing all the time, all day, every day. I've been in enough athletic and mental competitions to know that is just not realistic. So it bugs me a bit (just a bit), when a character only has at will abilities that can always be done all the time.
