I was a bard. Got into a level 77 dungeon. I hit level 80 from killing two bosses and all the mobs. Suddenly the special fate by Stilltide pops up, so I abandoned that because I wanted my Frog Mount since the fate can only appear once every few days (Sure 3 instances, but I want my rewards BEFORE the instances are gone). If I would have deleveled because of other limitations SE has purposely put in the game, I would have been furious.
We already dealt with losing EXP and crap like that in Eureka, and it's a terrible thing they brought from FFXI.
I worked with people to get my EXP, but something came up that was much more important, and no one is gonna take that away from me without a fight.
If anyone tried to take this from me, they'll be the one croaking.
