Why not add test dummies south-east of Prontera similar to the eggs inside Izuldes academy?, the area looks suitable and I believe they have this feature on kRO, theses also a Kafra that only has the teleport feature, shes literately next to the test dummie area, why not also make her open the storage instead of just only teleporting.
I think this will overall be just an improvement and having access to your storage right next to the dummies would be really useful.
