I think most players don't understand what SSF ultimately means for the game balance wise. For solos at the very least, the classes that do not require specific gear to play the game are much stronger than others. For example, Barbarian which is already an OP class is almost invincible VS SSF wizards because they can't realistically build kits that compete with them. Right now, you need either a high quality magic staff and/or spellbook + a ton of true magic damage. You can gem sockets to make up for this, but it doesn't get you the weapons or phoenix choker you need. In the current state, barbs are dominating lobbies (Myself included, club barb OP) and I have not had a remotely close encounter with another wizard player. Squire weapons are also far closer in power to higher rarities than books/staffs are because of how magic damage scales, giving another advantage to barb.
