Like: A dampened form of Overdrive once every 10ish minutes. It would be much better than Cooldown at any rate.
Dislike: Some of the suggestions for two hours are a little too ridiculous. Keep in mind that some 2hr's in this game are still pretty timid (Blood Weapon, Eagle Eye Shot, Azure Lore.... Blood Weapon.) There were some really good concepts thrown in and around but most likely would only get in implemented in parts rather than as a whole.

Keep the ideas comin (I still say extend the duration at the very least)
