If its 5 bucks for 2 retainers and its capped at you having maybe 10 tops (including the "free" 2) I would be ok with it. 20 bucks or so for more space is fine, considering how much space we currently have, I can see charging a premium for more since it does increase storage space for our characters server side, and even though its not expensive, its still not free.

Fantasia potions? Again I am ok with a few bucks for one of these. Your re-writing your character on the server in a sense (even though its dead easy and simple, but still) since race is probably tied into a LOT of things server side.

Charging 20 bucks for "Leet Dodo of Flaming Feathers" mount? So not ok with that. Never, EVER want to see that. I hope SE understands the difference and doesnt go into charging for "vanity gear and mounts".

Charging 20 bucks for 20 potions to refill your rest or give you bonus XP? Nope, not something I want in my games ever. Keep it far away from a "Pay to Play" game.

Services are ok, storage is ok. Moving beyond that is not.
