I don't have the energy to think about all that right now, but I'll disagree with point 6. The great thing about totems and summons is that you can make either physical or magical damage summons. Summon on blood or no-surface, and you get a pure physical damage dealer. Summon on an elemental surface and you get a pure magical damage dealer. You can already pick which armor type you want to focus on, changing elemental summons to physical with minor magic would make Summoners less flexible, not more.
