i think different games work better with different systems, however my favorite is halo reach, where the shield regenerated but the health portion didn't, so you'd have to go find health packs if you wanted to refill your health.
otherwise your just going to be camping the health pack spawns online with no restoration, and with the shield restoration you actually have a chance if you don't see the other person first, especially in long winded fights if someone is trying to melee you or such (i've had a couple 1 v 1's at the end of a match last a solid minute or two with the shield recharge helping in the strategic part of it.)
