I mean, maybe it's meant to... maybe I have to actually sit constantly playing or the numerical value of my rank decreases and I'm meant to slip down the ranks. Earlier today I ranked up to Voidsteel, got the rewards and the title. Took a break and then came back to the ToT ranked screen to check the Daily timer situation and now my points are 940/1000 and I'm in Quicksilver again. I haven't lost any matches because I haven't played any I was doing a couple of dungeon runs... I assume the aim was not to make players choose between other content and ToT XD
