Please stop comparing between different games, since each of them have their own rules/interpretations on how their elements work (jobs included).

I'm not sure that this is supposed to mean. Summoner has been the same in every game in what it does. The only difference would be the duel jobs some characters had, like BLM/SMN or WHM/SMN. FFXIV has been the game that has had it's own interpretation of summoner. And currently its a bargain bin Warlock from Warcraft.

Also Scholars and Sages shouldn't be your go to comparison since those jobs are not common FF jobs...
