I've run plenty of games where optimization pretty much required breaking the rules... amongst them, Traveller (Classic), Starships & Spacemen, T&T 5e, BX D&D...
... All are roll atts in order, then do the best with what you have.
I've also run a bunch where it was quite doable to optimize highly: GURPS, Reichstar, Hero System, Rolemaster/Spacemaster.
I'll not that not only does Stan Long expect optimization, he even put guidelines and breakpoints in the Hero System Rules 4e and 5e rules.
Any game with choices in CGen or Advancement has optimization space.
I don't see minor optimization as an issue. But I've played with too many who will sacrifice concept for maximizing some aspect... Sometimes even an aspect the rest of the group said "no" to.
