As many already know arcanist are getting both summoner and scholar when they leveling up.I don't realy like that way because that way a person that plays summoner can change to scholar and going into a high level dungeon and not even healed before.

Instead I would put the levels onto the soulstones that we get at lv.30. So when you for exemple leveling a arcanist lv.1-30 then choose to play summoner you get the summoner soulstone that will allow you to level summoner lv.30-50 and when you done that and decides that you also want to give scholar a chanse you equip the scholar stone and you again need to level 30-50. This way you atleast need to play the class before joining high level stuff.
