Stamina is a mainstay of the FPS environment, but we have a unique opportunity and background story to capitalise on this feature - the "humans" in Empires have all been either nanotechnologically or genetically enhanced. Let me just introduce this idea: Stamina can be used in any number of very cool and interesting ways in Empires if we just change the idea from "stamina" to "bio-energy". There is a large justification for this in both the story and background of the entire game. I don't know exactly what could it be used for, but I do know it could be used as a deployment mechanism for skills and abilities that are in the game and could be worked into the game; stamina already lets you run fast as long as you have energy, there's no reason not to expand it to other things when you're dealing with the nanotech and genetically enhanced people of Empires. I believe this could be an very worthwhile mechanic if we can brainstorm a bit about it - there currently exists no mechanism to "activate" abilities which would drain from a temporary pool of resources. Currently we only have passive skills and nothing 'active' except sprint. Skills like "dig-in" have conditions on them, but we don't have the scope of abilities that could be activated. For instance the grenadier's passive mine detection - it's rarely useful for a 4th weapon slot, cannot be buffed because it will be overpowered and make mines useless, so it remains fairly niche. But what happens if you could make it an active skill, have it reveal mines around you - to all players on the minimap and the local players on the gui, but at the cost of stamina. It's not a great idea (the mine detection), i'll admit, but it touches the surface of what could be done. Short, more useful abilities, at the cost of one of the most vital resources - your movement/jump ability. It would surely make a perfect justification for being 'winded'.
