Where are a people getting info about MAG being removed?
In EVERY gameplay video there is a MAG, there is even a WORLD Mag, which gets fed like the clan tree!
All they have said is there are new functions coming, with a world terminal being one.
If we are going from the same assumption then we are going to be limited to basic swords, knuckles, wands, rods, rifles and mech guns.
We have been shown characters in dev mode, with the most basic gear possible, that includes MAG. So we are only being shown the basic MAG.
I can't see them removing the stat aspect of mag, modifying I maybe but given that it's going to be our companion and main interface, I'm expecting it to be a decent part of the game.
As for pso2 not having PMs, we do they are called auxiliaries.
Only this time we can actually equip and style them, and they can help with collection quests and come in as a partner card npc.
