Return of Reckoning

I know that Tome tactics aren't in the game, I thought of a way to add some QOL items that can help someone without adding abilities etc that would not change balance etc. You could use that 5th tactic slot for special tactics you can earn for like RR80 etc Something simple that would be just kind of "nice" like "instant mount while out of combat" along those lines. Anyways, thanks for listening, just an idea i had on the toilet...
