Changes to Older Dungeons and EXP

[Naoki34]

Having just returned after a couple year absence and I see they've updated a lot of older dungeons for use with Duty Support system... in doing so, they've removed a LOT of the mobs to tone them down.

I also see that they made changes to dungeon EXP so that it's only granted by defeating bosses, but have they made the EXP higher with this change (due to removing mobs), or lower? I used to level up my characters using Squadron dungeon runs, so I'm curious how these changes impact EXP gain via dungeons with Squadrons, Duty Support and Trusts.

Do roulette leveling once a day, end of story.
(1/3 of the exp bar whatever the level, that's several M Xp lvl 80+)
