Revenge? Sorry, Revenge is always pointless from my point of view... And revenge is not the Jedi way... But this is my experience.
As Rebel, I hope every Imperial to hit 100% my base and give me the 16h protection, and I can open my Crates and collect my resources in peace. As Imperial, most Rebels attacking my base fail miserably against my Rodians and Bursts, they give me lots of medals every day -- why should I revenge those poor bastards?
Revenge is for those below HQ 5 without the planetary, then you know the attacker won't run away to another planet... Then you attack him, he will attack you, and you will atack him again, and this never ends until someone build the planetary and leave the planet...
If you are looting and can't spend everything you earned, you won't stay on the same planet waiting for someone to come revenge, you will move to another planet where you use to be attacked less, and try to save your resources.
If you were attacked, you won't lose your protection only to revenge -- and if is not for all the rival loot is pointless -- you'll lose protection and become available to be attacked by others or the same player will revenge your revenge. If you keep waiting until your protection run out of time, the attacker already relocated or is under protection, or online again...
Revenge is useful if you want loot, and some big guy attacked your base and you can revenge him and get more loot than you use to have looting normally in PvP.
Better than revenge is put a feature in the game where you can challenge other players, if they accept, you guys can join an endurance tournament to see who has more victories over the other.
