I strongly encourage any guide-writers out there to include their source(s) of inspiration. Context is super-important to understanding why something works or doesn't work in Dota. I don't think anyone loses out by the writer providing the environment from within their ideas originated such as their MMR, ranked vs. unranked, how much they've played this hero, etc. This isn't to say every guide has to come from a high-rated player or subscribe to conventional logic. Like, let's say I have a super-high win rate over a significant number of games with something super questionable like Deso-Bfury BH against 2-3k range players in unranked. Someone playing in 4 or 5k Ranked or whatever can safely ignore my post but maybe some casual player who really likes BH might want to read it to see what play style techniques is enabling me to win with those dumb items... I don't see how anyone loses out by my being upfront about where I'm coming from with my BH guide. Of course that's just a dumb example to demonstrate my point which is that one's "creds" are important. I don't think anyone thinks that only players of certain MMRs have experiences worth sharing, but it's nice to know if a guide-writer has a ton of time on their hero or if they just won a few games with whatever items and are popping into to say, "Hey guys, Blinken's Sphere WR is amazing!" or what-have-you.
