Equipments are ruining my mental peace

The constantly changing meta is making me fear upgrading an equipment to max. At one point giant gauntlet was the best equipment ever. And all of a sudden people are saying spiky ball is the best and giant gauntlet is useless. I've invested a lot in that equipment. And now it's useless and I have to upgrade another epic? I don't use money in this game. So that's going to take a while for me. I already have other epics to upgrade still. I finally collected enough starry ores to upgrade an epic. But I'm afraid coc is gonna nerf that too and it's going to be useless. This is too frustrating
