... it's just hard to think of a simple system that accounts for and mitigates the large difference in prowess a few levels can make, especially for casters.
I agree. I wish I had more to offer as to the specifics.
Regarding casters, there should be a spell cap. That is, no spells of greater level than the adept engage level may be casted for the duration of the engage.
Melee is more problematic, alas. As I mentioned above, there will always be twinks. The best way to counter this aspect, it you wanted to, would be to ensure that the further above the engage level the more severe the decrease in power. As of right now the proper range is 4 to at the most 5 levels below the adept. Scale the debuff in a way that, for a level 42 engage, a level 47 character would be on par with a 37 character. This would help to keep the encounters challenging.
I wish I could offer more specifics as to the % and the scaling. Frankly, I don't have the ability to test such things.
Thanks for reading,
