I support this idea, but not for the Foundry, where teaming is wonky. Maybe if they fixed the teaming issues.
I am actually more in favor of a system where Foundry authors could contribute by creating Fleet Eventesque missions and submitting those to a different tab. Those missions would have stricter definitions of what "qualifies" them as well. They reward the FM/XP the story missions offer the Dil/XP.
Middle-road strategies are typically not the strong suit for Cryptic, rather they do sweeping changes.
