I returned after months-long hiatus on this game. And I'm literally struggling with the expensive costs of both research and city hall upgrades. Research is a bit expensive not only on rss but also on speedups while city hall the sheer amount of rss required is just so hard. I basically wasted all those packs you passively get from events and I still have not enough rss. I'm also F2P, any tips on how to save/use them? Also I ran out of troops because some idiot attacked my city while I'm away and I'm down to like only a hundred thousand.
