I'd like to see a feat to gain attack of opportunity for my eidolon. A lot of the fun for me in playing melee characters is using attack of opportunity to deny options to the enemy and protect the back line, but that playstyle just isn't available in the Summoner in this version.
Is attack of opportunity something you'd take, if you had the option? For me, the answer is yes. But I'm curious if I'm the only one feeling its absence.
