Ahhhh SCB's
If I may, Id like to link to a small video which I recorded back when we were in alpha. Whilst of course things have changed since then, the general tactics if I were flying in this situation would be similar. The relevant part is from 4mins onward where in the Sidewinder I engage a wing of 4 ships. Gimballed lasers made this scenario rather easy, but nevertheless I needed to be careful and think about what I was doing.

If I were to do the exact same scenario above but this time with shield cells fitted, all id need to do is basically just target each ship one by one and shoot them to pieces individually. No tactics, no thinking, no strafe drive or FA-off stuff, nothing. Just turn around and shoot till they die. Pick a new target repeat, and spam some shield cells.
Personally I think they should never have been introduced to the game. That being said, I just cant see FD removing them now. Perhaps get rid of all the large module shield cells. Have them only in size 1 and 2 variants making them useful for the very small ships (eagle, sidewinder, hauler etc) so that the small ships arent vaporised quite as quickly against a larger one thus giving a slightly longer engagement curve. Also makes them useful while players are new and learning the ropes, but for any serious PvP or PvE id remove them. There shouldnt be the safety net, its easy enough to survive as it is imo.
EDIT: changed some stuff.
