Tornado Kick's potency is 420. The current shown is a bug. You can test this yourself by comparing damage to SSS. It still doesn't fix the issue. It's a move that eats all stacks of GL. The trade off must be worth the time invested which is at minimum 4 WS and a 2 minute skill, or 12 WS now. The only way to balance this and have it still eat GL is give it a potency of 700-1000. That is massive for a class that is usually running +40% damage but it's the only way for it to be balanced and worth using on a regular basis.

Anatman having a cooldown more than 10 seconds honestly doesn't make sense. It's only use is to maintain GL, it doesn't generate it as fast as WS except for a server tick exploit, and is generally clunky to use. It should have a low cooldown and gotten thirty levels earlier.

Chakra has always been clunky and more so since removing IR. The whole system needs to be reworked.

Adding more charges to the few oGCD we have doesn't fix Mnk's core issues. It has no directions, and the core systems are clunky and hard to use.
