This bug is still exist? Because some fixes for runes are applied a ~1 month ago. What exactly was fixed:
- When spell that costs a runes failed to hit (parry/dodge/miss), runes was going on cooldown (visually).
- Death runes now don't back into normal runes, when spell is failed to hit (parry/dodge/miss)
- And some fixes in rune regeneration, should be better overall.
