No thanks.
Allowing all learned actions in syncked duties requires one of two things:
A) At-level players will do 0.2x to 0.5x as much damage as syncked max level players because extra actions directly correlate to extra damage.
or B) Syncked max level players need to do 2x to 5x as much work as an at-level player to do the same amount of damage because syncked players need to have their damage scaled way down so as not to make at-level players' damage irrelevant.
Neither of these options is appealing.
