I noticed that when using illusions (wood elf, human, dark elf... etc... really anything larger than the size of a gnome, or taller) that the illusion remains small like a gnome, as if shrunk by the shrink spells. This only happens on my gnome warrior... This is not the case on live, they are of appropriate size when used unless i use the shrink spell on myself after turning into something taller than a gnome.
My barbarian shaman returns to regular size after applying an illusion, shrinking myself, and removing the illusion. However, if i shrink myself first then illusions will remain shrunk as well, and I would not have to reshrink myself. This is not the case on live, and not sure if it is an improvement or not... but I don't mind it

It is also worth noting that the size of the race you are fixes the size that illusions take on... Illusions such as the Trinket of the Hraquis hunter are currently all the same size regardless of race on live, but on the test server the size of the illusion is based on the size of the race you are. So barbarian Hraquis hunters are larger than dark elf, which are larger than gnomes. (Confirmed using my dark elf necromancer, Taladar).
