I feel like some people are forgetting that the Echo is implemented to help people catch up and get access to more content...and honestly, speaking from experience, TEX is still something I can't beat, even with Echo, for multiple reasons (other than me not being that amazing of a player). I don't have the fastest reaction speed and due to some mental stuff I get distracted a lot easier than I should (as in, I lose focus the moment someone talks to me on Vent and plumes eat me). There's also the fact I'm from Europe, which means latency can get pretty bad at points, for me at least.

My point is, the Echo is not some magical buff to help people insta-win things. It's supposed to make things slightly easier sure, but it's not a free win card like some people like to claim it is and while I think 20% on the first Coil is a bit of an overkill, I understand SE's reasoning behind it.
