I feel you should have different shields due to the fact its almost impossible to revenge because they are either online or have an active shield. This is how it will work.
You gain shields from being attacked as usual but can still get revenged if you don't have a revenge shield.
Revenge shield lengths are given according to damage percent same as regular shield.
Also you if purchase a shield with gems I.E one day shield. It covers both shields meaning you just can't get attacked at all because you have both shields.
Knowing SC is a Business and needs to make money they may make you buy the shields separately lol.
So what do you think?
