mana potion: discrepancy in secondary effect values?
so i'm playing on the oceania server, and mostly in survival if that's relevant. i noticed that the secondary effect for consuming a mana potion says it restores an additional 2.5% of your max mana per second; but on every hero i've used it on (Midnight, 190 mana; Zoey, 285 mana) what i've seen is that each tick of mana per tick goes up from 2 to 4 or 5. i thiiiink each tick is about one second, in which case the mana potion would be restoring more or less exactly 2.5 mana per second.
the boost is still really nice to have, of course, but i'd expect that if it were a percentage, Midnight would be gaining about 7 mana per tick, and Zoey would be gaining about 9 mana per tick. is the consumable description incorrect?
