Experienced summoner here, currently working on turn 5 coil. Almost full ilvl 90 gear. Posting as a formal request to change the way DoT's work in this game and get some feedback from the player base.

I would much rather (at my own discretion) refresh my dots than have to deal with not being able to refresh over more powerful dots in fights and actually having to let it run out.

Scenario :

You have loaded Miasma 1, 2, Bio 1 , 2, with a potion active (or virus on boss etc or another CD) , you then go to refresh (and attempt to time the dot to refresh) with 1-2seconds remaining left on the existing dot . Ie. replacing refreshing bio 2 with bio 2.
