Everyone knows that when two NIN's use Trick Attack right after one another the buffs don't stack they overwrite one another. Same with Ranged's Defense, DNC's Technical Step buff, and I'm sure there are others.

What if instead of overwrite or stacking so that Trick Attack now did 20% Damage Increase or DNC's buffs suddenly giving 10% or 15% Damage Increase to the entire party, they instead added to the duration.

So if 2 NIN's used Trick Attack back to back instead of having a 20% damage up for 10s the mob would have the regular 10% damage up for 20s. Same for the other things that don't stack.

This IMO would help regular players out that already don't care about the overwriting and Raiders would still be able to plan out when they wanted each party member to use what buff.
