Stuck in the 90s
I suggested they base the limit on Intelligence. 1 + Int mod (minimum 1), rather than a flat 2/rest. I can always make that a house rule, if needed. I suppose I'd probably have to do the same for the druid's wild shape, though, since that has the same arbitrary limit. I'd base that on something other than Wisdom, though. Maybe Con mod?
I'm actually a big fan of that at my table; changing limitations based on the type of campaign I'm running. In example, for Barbarian Rage, I convert it to rounds per Long Rest if I'm running dungeon crawls with different encounter types and sizes, affected by party size as well. The higher damage the party delivers, the more awful a 2/day becomes. However, 5 + Class Level + Con Mod per Long Rest (slightly less overall) is much more effective for the Barbarian when the fight ends in 2 rounds against a horde of Kobolds, and 9 rounds against a regenerating Golem. So good idea, I'll keep in mind for the AA.
