I started playing League of Legends this year and it seems very different to CSGO in being so varied in its balance that its far harder to predict who might win, thats just the appearance to me because I wont have the knowledge over years.
   CSGO I have bet for over half a decade off and on and its very much a game I would hope to predict reliably so long as the team performance is there, while we're off LAN and more distance I find CSGO bets are much harder.  I'm not sure if you have found something similar yourself in results, to raise confidence in your service I would suggest the occasional free bet give some time before the game so people can know you are on the level with your likely prediction ability and ROI.   I'll add your twitter to my list of people I follow for betting as im definitely still picking up LOL contests.
