Require a completed savefile.

I think a lot of the popularity of the gauntlet category is because it's played the same way many people enjoy e8 normally; with a full savefile and without lunars. Taking away some items would also take away a lot of that fun.

Besides, if runners want to do eclipse 8 speedruns with an optimised savefile they can just compete in the normal eclipse 8 category, the only major difference is that lunars are allowed.
