I want to officially go on record and endorse both Hairy and his … um … back … on this important, important issue. I completely agree and will probably get the third trait.
However, please make Keeper’s summon as awesome as he is.
Or change the trait?
I have it! 
You could change the trait to something effective, yet balanced … you know … like … like a summon that instantly devours the whole other team upon activation…
…and then goes after their families …
Ok, I might have gotten carried away. But right now summons yank so much that I occasionally lose perspective…
Understand that on the Bromantic scale, I could see myself cuddling under a blanket with Keeper, in a survival situation. I mean our life depends on it right? Pass the blanket, bro.
In short,
Keeper … goooooood …
Third Keeper Trait … baaaddd …
Summons … unnngooood …
