The abilities of the "clones" category should not be removed, but be changed, because they complement the play as a mechanics wonderfully.
The damage should become massively gedrösselt and or decay times should reach to hold a balance that remove is a big mistake, because invocation and object show to abilities a supplement of the diversity and permit a lot of mechanics, make useful and develop thus the variation. Duration and variation of magic on the basis of the clone landlord should maintain. Regularisation are carried out with damage and decay time.
Besides, certain combinations and Movesets must be avoided as for example the elusiveness as a slot with the clone.
Blizzard maintains this interesting mechanics and works on filling in her instead of them with any stopgap and on substituting further with dull standard magic.
