I've been working on a hexblade rewrite that grants maneuvers instead of spells with the crusader's mechanic (and some homebrew disciplines I came across). And I've seen ranger rewrites do the same. Over at EN, I found a thread where some one was contemplating granting warblade progression and recovery with Devoted Spirit, Tiger Claw, Stone Dragon, and Desert Wind to a shapeshift druid.
How do these changes affect the games in terms of balance? Obviously the Druid isn't king of the hill anymore, but would this move the hexblade and ranger up to tier 3? Would you see other casters changed to initiators, not necessarily the wizard but the blackguard or assassin? Or does this change only really benefit (or just fit) a handful of classes?
