Slept-on Mulan/Pele tech?

So Regrowth Striders are a pretty decent item, but with Mulan and Pele they have the potential to be pretty bonkers in long sustain matches.

For Mulan, when you put down your Training Grounds flag and face it, you gain movement speed. When you face away from it, you lose the movement speed, thereby proccing the heal from Regrowth Striders.

That means, if you're sieging a Phoenix, placing the flag behind you in the lane and turning to look at it every 10s will get you an extra 15% heal for nothing. This also works with any of Mulan's allies too, as they gain/lose the movement speed too.

For Pele in her aspect, you heal with Fuel when you press her 3. Obviously the trade-off here is that you can only get Fuel with Pyroclast or being hit, making it a finite sustain. However because you also gain movement speed while in your 3, you can also use it with Regrowth Striders nicely.

Fire your 3, then instantly cancel it. The movement speed will go away, proccing Regrowth Striders, and you'll get the heal without using up any of your Fuel (maybe a small amount).

Obviously both of these are kinda useless in teamfights, or when you can heal from other sources, but they're weird little interesting that work well in, say, Assault, where sustain is king.
