I'm not sure what to upgrade next in my base. I'm currently upgrading my last level 5 mortar to level 6, but after that everything else seems to have a cost of over 1.5 mil. I have to upgrade one last AD to level 5 (the one that costs 1080000 to upgrade). All my archer towers are level 8, and all cannons are level 9. My wizard towers are level 4.
What should I be upgrading first? I'm thinking the archer towers since they cost 1.5 mil, being the cheapest ones. But after that, what then? I could use some tips in upgrading and maybe even on how to farm better.
