2700 with GladiatorSuite. It's pretty solid. Few things I wish it did better but you can get high ratings with some decent awareness / communication.
I can vouch for this. And I cannot stress enough about decent awareness or communication, the CR will NOT carry you to any high ratings and let you sit back and relax. You still have to position yourself well, CC at the right time, and pop defensive/offensive cooldowns at the right time. But other than that, the hunter CR is extremely OP in arena. I am currently ~2600 in 3s and a high 5s rating using it. (Edited out my rating because you could find out my char just by checking ladders)
Hey guys, why exactly is GladiatorSuite better than TuanHA? Also, what settings do you need to change to get the most out of GladiatorSuite? The settings sort of confuse me to be honest.
Settings for glad suite? Bind every hot key in the class settings and for every ability that has a bind disable that abilities auto function in the CR with good placement, communication, and IMO most importantly good teamates, enjoy your 2k+ ratings. Currently 2.5k in 3s on 2 of the Gladsuite CR's. Cokz and Tolzi have an incredible product and are very responsive and nice about feedback at that. I gladly gave them my money. Worth every penny.
