That's not the argument being made I think veekie, otherwise you'd be right. The argument is in two different builds, both identical save for where the levels are taken, being different in power, which I think is a bad thing. However, this is not a fault of the individual classes or the characters in question, or even the mechanic itself. It's an issue with the execution of the mechanic and the individual maneuvers. Again, though, fixing this is incredibly easy: allow PCs to retrain their maneuvers at any time regardless of the class taken. Not all the time, but most of the time. Be smart about it, and let them retrain obsolete ones so that they are effective at all levels.
