I see where you're coming from Dvang and argue it well, but let me make a slight clarification.
What is so bad about a trained soldier who knows how to get around armor spamming the same attack? Wouldn't he try it at every opportunity he gets? Wouldn't he constantly do it rather than hit hard. I mean if you come to a fight with a sword, a knife, and a machine gun, which one's are you going to use? You'll spam the machine gun till its out of ammo, go down to the sword next...if and only if that breaks or you're disarmed, your opponent gets to close you'll go down to a knife and only if that's lost will you down to a your fists, and if those cut off, legs and teeth. Maneuvers with those weapons are spammed until they are countered or are no longer applicable (gun runs out of bullets). A guy with a machine gun fires, fires a lot, sprays or short bursts. Sure he can switch between them, but does it at his leisure. That's just how it goes. If you try to split logs you spam the same action over and over and over again for each log. When you do most actions, you find the most effective way of doing it and spam. You may stop when tired, wipe the brow, then get back at it. It's simple nature that when you find the best system of doing something you do it until someone else shows you a better system.
The recharge system is counter-intuitive to that effect and natural system. I'll go into that a little more, but I gotta run, so I'll get back to you.
