I think some people here have never seen a really good shield pack dueler. It's not like they keep the pack on for the entire battle. They quickly flash toggle it to absorb a disc or mortar and then release it. Trust me that if you give top cappers the same energy with a shield pack as an epack they're going to find routes that get them to the flag fast and with lots of energy to spare.
There's ways of making other packs useful while keeping the epack. Maybe make the epack not give you such a drastic increase in energy. Have the shield pack take 1/2 or 1/4 damage from self-damage so it could be like the disc jump pack.
On the other OTHER HAND if it could be balanced, making people have to utilize a non passive pack while handling their weapons, jets, grenades, and whatever else could add a significant amount of skill to the game.
