Optimized and powerfull characters are fun! When people complain about "powergaming" they are bad dms who don't know how to properly dm and react to their players. They want set pieces that have to follow their orders. Same thing applies to players. You can play off meta builds and that's totally fine, but don't try to controll the other players and make them feel bad you are gimping yourself
