The problem is the fighter should not even know, nay no one should; that they are in need of healing.[/quiote]
Ah. You see, I expect many of us hold the opposite opinion. The fighter is a specialist in combat. Hitting and getting hit is what he does for a living. If there's anyone who should know exactly how much he's got left in reserves, it'd be the fighter. Because if he doesn't know that, he can't apply decent tactics, and if he cannot do that, he's dead.
Though, honestly, anyone who gets into a fight regularly - meaning all the PCs in a typical D&D game - ought to have a clue. Heck, in the real world I only put on armor and whack people with sticks occasionally, but I know when I'm getting too wiped out to keep going. |
