....Did you just quote Rumble? <3
Personally I like this one: "Experience lad, you should learn to appreciate it", -Kup
Couple things: jetpacks don't need shield diffusers. They just need entry points only they can reach (more easily than others) as a shortcut or bypass. Shield diffusers should be something purely for infiltrators. You then get two distinct ways of bypassing a shield: over or through, where the infil infiltrates directly and the jetpack takes a more creative route.
Tbh, I would have said remove jetpacks entirely or limit it to dependency units (like how the VS MAX, the only unit with backpack, couldn't enter buildings in PS1 and required the help of an unwitting enemy, mossie dropper or gal drop to open up access to the inside from the top), but hey.
