How about a burst type jump jets that give you one huge boost (vertical), so you basically make a super jump and the jet-pack becomes depleted. Intended purpose would be to quickly go on top of buildings, jump over walls, jump on trees and move fast when trying to go in a bee line somewhere, but at the expense of actually flying (If the jet is fired midair it just "stops" the LA (ie. he can't hop while in air). To compensate the jet-packs would recharge much much faster so there would not be much downtime between jumps. P.S. Inertial Dampeners (Suit Slot) - i would like this on the infiltrator as well xD. Other than LA inf is the 2nd class that HAS to jump from high places on a daily basis. P.P.S. Now that one can not ADS while jumping i could imagine a suit slot to re-enable LA ADS while flying... cheap i know, but its better than not being able to do it at all.
