Im currently struggling on which to upgrade first. Im already at around 3800 might. Im focusing in upgrading resources and vaults. Was just wondering when is the best time to upgrade towers. Right now i have 3 archer towers. Because im afraid of upgrading them since this would increase my might in a huge way! And i don't have legendary heroes yet.
At 3800 might defense means nothing. You can just raid back 10x what you lost in 10 minutes. Upgrade them whenever you want to. They don;t increase might by that much. Things I would stay away from if you wanna keep a low might level are: troops, walls, TH, and Spells. The Spells and troops jump your might so hard it isn't funny. Getting lvl 1 FD's gives you over 300 might and each Spell upgrade gives you over 40.
We got one of those. I'm not sure that it's finished but I will try to keep updating with higher level stuff.
Here's one of them:
