Wouldn't mind some changes. I'm a fan of the long cast time summoner myself. 4sec casts and multiple zeros at the end of the damage number.
Don't know if splitting off SCH would really truly change much. We share similarities but theres not anything really linking the two. It could be cut off either way i suppose. If they did, i certainly hope they would give all the books to SCH and bring back a fairly underused SMN weapon.
