Serious game play problem with possible solution

[Jamillion]

The DOT limit is 60.

I highly doubt that all 24 people are using enough DOTs to reach that limit.

I use SMN in Void Ark and even though sometimes I can't see the duration of the buff, it's still active since when I use Fester it does full damage.

You'll know if a dot doesn't apply because the floating text will say "no effect". If you don't see that, then the dot is applied even if the display doesn't show it

I've seen trick attacks get used but fail to apply with under 20 applied statuses in Void Ark, never ran into that in any of the Crystal Tower raids.
