How is this a good RP design and how can anyone expect a challenging experience when you can literally fine tune your party all the time?
I understand you don't think the respec option is good for the game.
That said, I don't use the respec option, and I still walk through the tactician difficulty. That's what folks are saying. The game is currently too easy in tactician, even without using exploits.
Yes, exploits make everything easy.
But the game is already easy even without exploits. That's what I think a lot of people seem to be missing.
