That game is just badly designed. If no one from a base is active on the server, they shouldn't be able to get attacked. Period.
Allowing all your hard work to be deleted just because you have a life outside the game is dumb. I'd never play such a game more than one session.
99% of games are definitely not a Sisyphean hell at all. You should broaden your horizon more.
