I have tried to find the answer on this forum, but couldnt find it, so here it goes.
Is leveling up mines and such worth the cost? Do you get more or better stuff or is the only gain a shorter cooldown. Which in case of a mine is about 10 min/level. I see a lot of high lvl players that didnt upgrade it, so could anybody comment on it if it is really worth the effort of leveling resource spots up?
Thx!
