Pets account for 30% of your overall dps. If you wanted to make that number shoot even higher, up to you 50%, then they would have to make pet management much more difficult so that players cant just turn on their pet and do half of their damage automatically.

The way it is right now we already get a lot of damage for how little we have to manage them and its silly to want more for the sake of sticking to past Summoner conventions. This isn't FF11, this is FF14 and a lot of people are satisfied with what we have currently and suggesting random changes just because they sound cool disregards those people.
