If anything, all the martials should have access to Maneuvers. Like the spell-casting classes, you balance them by having a curated list of which ones they can access, not denying access altogether. The fighter should probably have the broadest array (like the Wizard)*, while the Ranger's are more specialized toward certain creature types or anti-enemy abilities (like Regeneration, Incorporealness or vs. specific creature types). The paladin's list would be more limited to melee ranged feats, those for fighting fiends, celestials and undead or incorporating their "holy" abilities. Barbarians would have Manuevers that synergize with skills, saves or their rage ability - and perhaps some anti-magic capacity.
This is the case in Level Up.
