Got something to add:
Priest and Craplain: Make Exorcism and Magnus Exorcismus actually useable.
Krivis, Diev, Craplain and possible other classes too: Add a passive that prevents Aukuras, Statues and Capella from being pushed around.
Cleric, some higher classes too: Add a passive that prevents non-partymembers from stealing Heal, Cure, Safety Zone, Healing Factor and possible other effects too.
As for your attacks on Elememe… Nerf Quickcast attribute would kill Wiz3 and nerf Frost Cloud would kill Ele. Either class is played cause of the said skills working the way they do. Wiz3 is entirely played for Quickcast. Surespell and higher Sleep are bonusses. If you start attacking C3 skills, you should call for various nerfs of various other C3 skills too. Lets see… Melstis and Ausrine need a nerf to give Priest based support clerics a chance to see ET from the inside, for example. But that would most likely kill Diev cause the class C3 is played for that alone.
