Repairing bases is miserable

Repairing a basic wall takes more time than building the entire wall, and you get zero reward for it, no XP, no money, no nothing as you endlessly hit walls to fix them as a single player somewhere is shelling your base for the last 10 minutes and is single-handedly destroying an entire FOB, spawn vehicles, resources and everything else.

Also no information on how damaged a wall is, there is a discoloration for any way that is between 1 or 99% it seems which doesn't help players to figure out what to prioritize as you waste time repairing 99% walls.
