I am working on a homebrew setting for a campaign I have in mind, and the setting as imagined would pretty much cap out at TL 11 as the highest. Without having a ton of rules experience in this system, does capping the overall possible tech level mess with the balance/mechanics/intended character progression mechanics of the game? Would I be setting my players up to be frustrated that certain skills or abilities they may want don't work with TL11 gear?
