Because armor tanks would ***** and moan, its another reason why shield vehicles are bad

I have never played EvE, but you are saying that when you are in a ship to ship battle, you can duck behind cover to stop taking damage and let your shields recharge?

Maybe cause THAT's WHY.

Down here on the ground, Shields are regulated by Capacitors, these capacitors expend there energy in bursts to keep you safe.The capicators however are practically useless unitl they reach at least 70% charge, giving a burst regen.
This differs from the Space craft which just use giant energy banks, the energy banks are fed by a generator which provides a constant current giving a passive regen.

In terms of gameplay, if we name each cycle or recharge a tick, each tick lasts a second, now if you get shot during that second during passive regen you can loose all of it.
If you get shot during burst regen you don't loose any of the regen from that tick, therefore burst regen is more beneficial.

So you just want shields to function exactly the same as armor?
