How To Reduce Ping!
First of all... Hi! Bronze Scrub here.
The link I posted above gives several tips on how to reduce lag a lot! I personally have noticed a 70 ping difference, from 190 to 120. It wont just help league also! I noticed better loading times from everything across the board, even better YouTube video loading!
Since I personally only watched the first 2 given steps and noticed extremely reduce ping of 60-70+ I think this was essential to share to those players whom pings are really high. I also may recommend using Google's public DNS server.
Primary: 8.8.8.8 Secondary: 8.8.4.4
If you don't know how to do what I posted above check this video out: https://www.youtube.com/watch?feature=player_detailpage&v=BmkbFyfxh3k
Overall this drastically reduce my ping and hopefully I can help some of you out.
(P.S.: If you already have good ping such as 1-90 you will notice no to little difference in ping.)
