Right now Summoner doesn't feel like a summoner, more like a ruin mage who can also summon.
I would rather have my spell more focused on pet damage and pet abilities than speed spell spamming.
Changes to be more like summoning Bahamut, powerful but temporary summoning attack spells. Honestly, i wouldn't even mind not being to summon a permanent pet for more temporary ones.
Same with the DOTs if they were an effect of a summoned attack creature and such it would make summoner feel like a summoner.
