That being said, I have a few questions:
- What would be the best way to handle prereqs? Easy mode is to leave them as-is, but some could probably be lowered for this. Perhaps get rid of other feats as prereqs?
- Should the tactical feats (the ones you normally get at 6th level that grant three maneuvers) be left as-is, or should they be broken up into their separate maneuvers, with no/fewer prereqs?
- A lot of metamagic feats are pretty good, already. Is it better to accept casters getting solid benefits from this rule, or should something be done about any of the feats that are notably better than the other published feats?
- Any other obvious concerns I missed?
