PSA: Please check people's match history for solo que before trying them out.
I'm not saying this because I think you should look at stats or whatever, but because of the huge increase in boosted players I've noticed over the past couple weeks. Not saying names, but there are at least 3 posters on the Recruitment forums right now who were boosted. Some are around low-mid plat level and are currently low-mid diamond, which is annoying but not nearly as bad as silver-gold elo players who are sitting in diamond or high plat. It's generally pretty obvious once you're in game, but why waste 20-50 minutes of your time + champ select and que times instead of taking 5 minutes to go over someones match history and look for a summoner swap or a random win streak with a previously unplayed champion?
