Actually, the Crusader is probably the most broken of them all. If the Crusader picks his maneuvers carefully, he can actually have access to all his maneuvers every round once he goes through the cycle at least once.
I will break down how this works...
Here is an example of what happens:
Start of Round 1
3 Maneuvers GRANTED
2 Maneuvers WITHHELD
(Player does not EXPEND any Maneuvers)
End Round 1, 1 Withheld Maneuvers becomes granted as such:
4 Maneuvers GRANTED
1 Maneuvers WITHHELD
Start of Round 2
4 Maneuvers GRANTED
1 Maneuvers WITHHELD
(Player does not EXPEND any Maneuvers)
End Round 2, 1 Withheld Maneuvers becomes granted as such:
5 Maneuvers GRANTED
0 Maneuvers WITHHELD
Start of Round 3
5 Maneuvers GRANTED
0 Maneuvers WITHHELD
Player expends 2 Maneuvers (1 strike, and 1 boost), which now looks like this:
3 Maneuvers GRANTED
2 Maneuvers EXPENDED
0 Maneuvers WITHHELD
End Round 2. Going on the quote provided above from ToB... We have can not be granted a manuever because we have no withheld maneuvers remaining. What happens? I recover all EXPENDED Maneuvers (in this case, 2 have been expended) and a new pair (that means 2) of maneuvers is GRANTED to me. I already have 3 GRANTED Maneuvers, but a new pair gets granted to me, so I am back to 5 Granted Maneuvers.
There ya go. After 3 rounds of combat, you will have all your maneuvers available to you provided you can use at least 2 maneuvers every round.
