Yes please.

At the moment I'm toying with the idea of removing their default magic in favor of 'potential' magic. They would have no magic when you summon them but 50 gems empowerment of the appropriate type would get you direct to level 4 in a path (thematically speaking, it's just a different way of representing the feebled mind, but in a way that anyone could heal them, not just the GoH/Chalice). This way, with the right investment they could well surpass most EDM summons, but they wouldn't have the huge diversity advantages.

Yes, I think the only way to remove afflictions would be to swap out the summoning spell, which has side effects I'd rather avoid. I think having plenty feebled would still be OK though- it's true GoH/Chalice is great now but the concern with the direct raising prices was that it would make them better- this would just leave them at about their current power. After all, how many tarts can you really empower? At 10 gems each you should easily have plenty of healthy empowerment candidates. Also, under this tart scheme GoR could probably get cheaper and they could be used with whatever afflictions as thugs (I actually think seeing some still feebled tarts used in battle would be quite cool).

let me see if I get you right, your suggestion consists of:
1. Tarts won't have magic.
2. 50 gems worth of empower would give them lvl 4 of ???
3. Tarts would still have afflictions
4. Tarts summon price would be 10D
So basically to get a 4X tart I'll need to spend 10D *(avg # of times to get non feeble mind tart) + 50D. My gripe with the suggestion is that: a- it keeps the current unthematic "all nations take death to get to tarts" tendency. Yeah, it really makes sense to see MA Mari + Pyth deploy tarts and go hvy on death...
and b- The price raise and losing diversity seem to take all the fun out of tarts - or in other words are too extreme.
Except LA Ermor the other nations could use both diversity and row power. Think what it would do to MA Machaka status to have near exclusive access to tarts. So perhaps don't give Tarts to LA Ermor but do give to other underpowered death nations.
Tarts are fun the way they are but not everyone should have them. To prevent ppl from taking them you'll need to make them suck and then nobody will summon them
