Potion effects

Bislobo

I am using major expedition + major endurance + unstoppable potions on my Stamina Dragonknight, however sometimes the effects don't last the tooltip duration.
They only last approximately 10s (even the major expedition and the major endurance ones). And it's not a UI error, the effects really wear off prematurely. This happen very often, i can provide more details if needed, i am just pointing this out since i don't know if it is a know issue already. This happen in Cyrodiil, Azura's Star campaign.

Buffs can be overwritten. Someone drops a maneuvre in your group, potion buff gets replaced, you activate a skill, boom major expedition gone. This one is exceptionally bad if combined with a bow, since using a dodge roll while carrying a bow will reduce exped from 46 to 5 seconds.

Same for major endurance, a templar throws aura, which lasts 15 seconds instead of 46, boom potion buff gone.

As to unstoppable, probably same thing just can't put my finger on which buff it is.
