Alacrity in this game when it comes to dots, speeds up both the tick rate and the durations of dots (serrated,incendiary) or doesn't affect either tick rate or duration (electro net,fusion). For Supercharged Burn however, there is a negative relationship with alacrity where the debuff expires faster but ticks at the same rate. This results in missed ticks of damage when a raid wide alacrity buff goes out or a relic of primeval fatesealer is used. Please either fix alacrity affecting the tick rate or duration so we can have full damage from supercharged burn.
Below are screenshots from Mercenary and Commando to demonstrate alacrity resulting in missing ticks of supercharged. 1st and 3rd demonstrate dot's with 19% alacrity and 2nd and 4th demonstrate 11.6% alacrity.
