I would have thought someone would have done this already but I can't see it anywhere except in some of those "ZOMG Why doesnt Power Armour turn me into liberty prime??!?! FIXED!!" style mods. Any chance someone could just remove the run speed reduction, it's such an arbitrary penalty, it doesn't make any difference to the difficulty of combat, it's just an irritation having to constantly equip/unequip it for long runs.
Discouraging players to use more powerful items by making them annoying to use is not good game design ?_?
It's not bad game design, it's adding a penalty to using more powerful items. There are trade offs. "More powerful" shouldn't mean "Oh look, Power Armor, NOW I AM GOD WITH NO PENALTIES WHATSOEVER!"
Positive effects are (and should be) often offset by negative effects. That's part of the structure of classic RPGs.
Anywho, this gives me an idea... Hmm.
Edit: By the way, you could always bind a light/medium suit of armour to the hotkeys, and your power armour to another for easy switching.
