Why does this thread even exist.

Not to be rude, but it's not the job of people who can kill content without a huge echo buff to carry people who aren't good at the game through it. To be quite frank, pretty much all of the content that has echo is old and quite easy, so you're either A) Not properly researching a fight or B) Aren't skilled enough to beat the fight properly. It all comes down to shortcomings as a player, which is your problem, and doesn't constitute a gratuitous token system as a solution.

You just need to try, study fights more, and polish up on yourself as a character. Some would argue that the echo system, even as is, is kind of unnecessary. We don't need a token system, we need people to take fights more seriously, not faceroll through them with 50% echo. You'd be surprised how much a half hour of seriously sitting down and watching a video, and how it's relevant to your specific role, can do for you.
