In the Warpath passive tree, the Dark Nexus passive gives mana every 3 seconds when spinning. Similarly, Echo Knight passive requires you to spin for at least 2 seconds in order to proc an echo. That works all well and fine, however, I noticed that whenever you use an instant cast skill like Volatile Reversal, it doesn’t reset the 2 seconds timer on Echo Knight, but it does stop the mana timer of Dark Nexus and you need another 3 full seconds to get a tick, meaning that using Volatile Reversal on cooldown almost completely kills your only reliable source of mana regen, while it doesn’t affect the echo passive at all.
Not sure if it’s intended or an oversight, but it makes no sense to have Volatile Reversal reset one timer, but not the other.
