BUG - Warcry Mana Cost is COMPLETELY BROKEN at 0.18s Use Time Threshold

Use Time: 0.19s
Time before I run out of Mana: ~7.07 seconds

Use Time: 0.18s
Time before I run out of Mana: ~2.46 seconds

Meaning, my build gets bricked if I go under 0.19s Use Time. 😒👌

Here's a video that demonstrates the problem.

Edit: Seems to apply only to 0.18s threshold, at least as far as I have tested it at this time.

Bump for visibility. I hope this gets fixed in a future patch.

OH! Almost forgot! It should be noted that this isn't apparently an issue with SKILL SPEED, but with WARCRY SPEED only. At least I think so, because last night I had a Speed Shrine buff bring me down to 0.17s Use Time and my Mana consumption wasn't being gutted. Skill Speed stacks additively, as per in-game description. Maybe only the 0.18s Use Time threshold is bugged, I cannot confirm.

Oi! Can confirm this is specific to the 0.18s Use Time threshold. Literally just tested this with another jewel to get to 0.17s and it's draining my Mana normally at this threshold. Something's cooked.
