Honestly, a RGT just right after the EIC ended, to make the transition with the upcoming 2v2 would be an absolute banger.
15thYR, 92nd, 45thN, 13e, 71st currently all have a top 10 line-up that can beat each other on a good day. Obviously, there would still be some more favourites than other based on experience and consistency but it would be a proper shame if nobody comes around to host something like that. I believe people mentioned it a while back but I have not heard about it since then so I have no idea if it's being planned or not.
