I have always used the dash/down dash/down method to wavedash. However after recently coming back to marvel I wanted to improve my game, and plink dashing gives you the advantage of being able to dash backwards efficiently and use multiple airdashes quickly in the air. I use L, M, H to dash as I do not have a button bound to L+M, M+H etc. If it is avoidable I would rather not bind a button to dash for me.
What is the most reliable way to plink dash without using a separate dash button? Maximilian's guide said to use H,M,L but in the Jago's baby rehab guide he stated using L,M,H in quick succession. However in this guide it appears that you can do Plink dashing using just two buttons in quick succession using some kind of timing.
While I can sort of Plink dash it is far from reliable so any advice before I start trying to get the muscle memory down be appreciated.
