All a stamina bar would do to this game would be to make the lighter faster waepon users GODS of the game. There would be no point to using anything else.
Plate= there went your stamina
Polearm= stamina gone
2h= one swing no more swingy
1h= new spammer.
And let's not forget at long ranged weapns or throwers. Crossbows are the new sexy
Horrible idea. Talk about breaking the balance
Right now people have to actually waste attribute and wpf to use these classes effectively. And you want to take that away too?
You are right of course, because adding stamina would have to be done in a completely dumb and unbalanced way. Somehow, stamina couldn't be balanced and tweaked like all other aspects of the game, because...
If you can finish this sentence, I will start reading your posts again.
Stamina could indeed improve the game. Of course, strength would influence how much stamina you lose due to item weight. A strong character can carry more and swing heavier weapons without getting tired.
Furthermore, it would be a chance to remove the requirements on weapons. Instead of silly hard requirements, weapons would be available for everyone, but if you are not strong enough, you lose a lot of stamina when swinging it, making your second swing slow as hell. Would also be better for balance, because if some agi spammers abused some weapon, you could simply make it a bit heavier, so that they could still use it, but wouldn't be as fast anymore. Currently, you can either make the weapon slower in general, which also affects str builds, or you can up the requirements, which will render it completely unusable for some builds.
BTW: We don't need a visual cue for stamina, if your player starts to swing slowly, just stop swinging and running for a while. So we don't really need a stamina "bar", just the mechanism.
