@ OP

This is a singleplayer experience. If someone wants to respec, let them. It does not affect your game what so ever. Honestly this kind of one sided thinking is from the same minority who tried to say the same thing about Skyrim on release. This game has Online Co-op, where you need to make a new character to even participate. So someone who would use the re-spec mirror couldn't even port their character over to multiplayer to otherwise "ruin your game experience." The only person you ruin it for is yourself if you decide to abuse it.

Do not call it bad game design if you yourself plan to use said "bad game design" in the first place. You must've used the mirror at some point or another or else you wouldn't be here complaining about it. Something must've gone wrong in your game, so you're under the mentality of "Stop liking the thing that I no longer like." Not everyone feels this adamant about it. Being able to respec in an RPG. (Role-Playing Game) is vital for players as it let's us approach the game from different viewpoints.

If you don't like it, then that's too bad. Nobody is forcing you to use the Mirror. Stop being pessimistic over a system that you clearly aren't forced to use and trying to bring the roof down upon everyone else simply because you're not happy with it. If you want a real hardcore experience, go play Honour Mode and come back to us since the game is too "casual". As a matter of fact.

Idea Proposal: Respec Mirror is removed in Tactician Mode/Honour Mode.

For you elitist types out there.
