It is not even worth to try to compete anymore for ranking. A friend directed me to a website where there are tons of bots: Ghom bots, Bounty bots, Rift bots, of course Turbo Hud, advanced macros, etc... Call me naive but I did not think it was so extensive.
So I went to look at a well known Twitcher (Who got his account cancelled last season) and watched him play for a good 30 minutes doing 80+ GR. What an eye opener it was!!!
1 - The team of four NEVER ended up in a dead end while doing a GR. NEVER!
2 - It seems they knew exactly where was each pylon and each elite group.
3 - During the whole time I watched him, His eyes continuously went to his left. It took me a while to figure out what it was. I think he was watching one of his team mate steaming privately with Turbo Hud on.
4 - I noticed also quite some feasts of jumping VERY FAST out of trouble. He never was caught on the ball of an arcane. He and his team mates were able to jump very fast and each time out of ice explosion or ice orbs. I watched quite a few times Quinn and he is not THAT good like those players.
Anyway. I am just sayin here...
