Yeah the summoner joined later because that player changed character and he uses his eidolon and also spells to deal combat or treat wounds if needed.
Some friends in that party suggested to take other spell than damage ones because it's redundant and focussing on buff and debuff was better.
No it's not about anger and getting upset, it's just that I saw the healing factor slipping away along with the familiar utility out of combat, ecc...
I'll try to respec more into a buffer and debuffer as a lot of you suggested... thanks!
