Hello, I'm considering playing a Crusader in a new campaign. It's starting off as 1st level. My understanding is that I start off with 5 maneuvers known. As you gain levels, you learn more maneuvers (1 new maneuver every odd level). You can also swap out 1 old maneuver for 1 new maneuver starting at 4th level and every even level after that. Is there any reason at 5th level to NOT fill up all your maneuvers known? Looking at it, if you fill up with 5 1st level maneuvers it seems that when you get 2nd level maneuvers (at 3rd level) you can only pick 1 of them. I can't help but think it might make sense to, rather than take a maneuver you aren't terribly interested in, to hold onto the slot for when you gain a level to use it for something that might be better.
So my question is essentially does it make sense to hold onto maneuver slots in this manner? For that matter, is that even possible or if you have 5 maneuvers known, do you have to know 5, end of story. Thanks!
