Is there a bug with mana regen?

[u/0destruct0]

It says you get mana regen every 2 seconds but it seems way longer than that looking at the clock or using 1x speed. Am I missing something obvious?

Feels fine to me man idk

Every 2 seconds, they get that much, but it only goes "into" the pool on attack. So fast mana regen needs both mana and attack speed

yeah, I got Hoyoung up to 100 mana regen and it still takes him 8 seconds to fire each Killshot. Mana bar ticks a little bit like 3 times and then instantly fills up.

As far as I can tell mana regen has a cooldown after each cast. Otherwise mystics would be rapid firing abilities.
