At present, the abilities of T5 level monsters are clearly differentiated based on strengths and weaknesses. Going upwards, like the T3 level, it's hard to define specific grades because the creatures of this level wouldn't have useless abilities.
Take the un-promoted room 225 and the little baby for comparison, both are T3, just with different ability orientations. Hence, they're priced at the same level.
Obviously, such matters can be properly dealt with. In the future, classifications and pricing can be done using realms such as semi-C level, mid C level, the peak of C level, and the grand perfection of C level.
There's no difference, really.
