I think this game could use a warlock class.

I'm not sure you understood what I said...
Currently in the lore they've defined it so that egis constantly take a toll on our aether whether or not we currently have them out. Using that logic, we should be able to have two or three different egi out at the same time since they're draining me at the same rate anyway. So my point was that they introduced a plot hole by defining summoning in that way.
The fact that we originally we're going to get more egis but they changed their mind means that lore is just up to the whim of the developers and in the end it's just game design. I just think it's bad game design since it doesn't portray the image of a classic Summoner the way the other jobs portray their origins...

Here we go again, the "you disagree with me so you must not understand" argument. You should have a look at the link in my sig.

That actually makes a little bit of sense. Arcanists are known for using symbols and mathematical formulas for their magics, but somehow I doubt this will be able to be worked in the game mechanics

Nah, would be no problem. And in addition to that we should have some kind of a mechanic where the summoner gets eaten by a demon if they do one incorrectly, like the Rabbit for NIN but more serious.
