Which means:
Sera uses flask: Dps increase.
You use flask: No dps increase. Survivability + mobility increase. Good for flanking though.
I hesitated before responding this, because I'm not really trying to get into an argument.
But this statement bugs me slightly, as it's not wholly accurate. When you pop flask of lightning, and time slows down, in-game seconds last longer than the player's perception. If such a thing were possible in real life, and you looked at a clock, the second hand would be moving more slowly.
DPS, relative to the passage of in-game seconds, and relative to how quickly the baddies damage you, does increase.
But it is true that total time to kill, from the player's slowed-down-time perspective, does not increase.
Just sayin'
