Still cannot quickly see if my debuffs are on enemies.

Thanks for the feedback everyone!

Eeh... I don't quite like the removal of the timer on the other debuffs OR the outline. The removal of other's can be problematic if your choice of action is dependant on the other's debuffs and even if it is just a matter of five seconds planning two or three moves ahead is important if you got combos going.
And the outline is just ugly. I don't even mean your choice of color or thickness or whatnot, it's just... Regardless of the chosen color it will look like a deeply disparaging element with the rest of the UI. The green timer already does that.

The idea of increased size and organizing your own debuffs in the start of the list first is a good idea, however. That alone should do it.

And man single-boss FATEs in Limsa were amazing, two or three rows of debuffs

Well as I said in the OP, the outline and removing the time remaining of others debuffs would be optional. The biggest thing that would help is moving your personal debuffs to the front of the list and changing the color from light green (it's just too similar to the regular color for me). Maybe a size increase, but that could also be optional.

lol, yeah, the bosses in Limsa FATEs were insane with all the DoTs. :P

Ideally debuff display order should be your debuffs (big) -> non-DoT debuffs from others (ie things you might care about, such as Slow)->everyone else's DoTs.
