Is Dotabuff Plus worth it?
The new features are pretty alright. You can track your global percentile with certain heroes, and there's a tracker that tracks your mmr gain / loss and plots it into a graph so you can review it and see when you should be playing and when not (I.e if a trend over 2 months is that you lose games between 11 pm and 1am, you're either too tired and shouldn't be playing or that's when the scrubs come out, either way avoid it). Useful data I guess.
For the hero tracker, I found it abit odd that I have a high80 plus percentage on counted games on Elder Titan over 40 ish games, but I'm still only platinum 4 (platinum 1 being the highest, with a whole separate tier above that populated by streamers and pros). Struck me as odd, but maybe there are indeed many good ET players lol.
