Making Yasuo's Flow into a unique resource
Flow generates in the same way as before, except now it generates twice as fast. Same values as before, 100-510 based on level. The biggest change in the shield is that it can now be activated at any amount of flow, not just max, and has a cooldown of 17/12/7/2 seconds at levels 6/11/16. So at level one if you have 50% of your flow gauge filled and someone autoattacks you, your Flow will be consumed and you will gain a 50 health shield for 1.75 seconds. You will then not be able to gain the shield for another 17 seconds. The Flow bar is white when able to shield, grey when unable.
Q now costs 10/20/30/40/50 Flow. Autoattacks generate 5/10/15/20/25 Flow, doubled on enemy champions.
W now costs 50 Flow.
E now generates 10%/15%/20%/25%/30% maximum Flow.
R now generates 25%/50%/75% of his current Flow and refreshes the cooldown on the shield. If he has max Flow at the time using his ult, he will gain the shield automatically for three seconds and retain the rest of the excess Flow.
Lemme know what you think and if you have any questions, any suggestions are welcome.
