"Yeah these key problems are annoying and I have an idea. 1. Only one kind of GR key to rule them all. 2. Completing GR gives GR keys, as currently on PTR, but only one kind of key, without the 'Level X' affix. 3. Pay one GR key to enter GR, the level can be chosen by the player, but with some restrict, see below. 4. Player can choose any GR level below their **qualified level**. Every time player cleared a level system calculate the next level based on their performance, if this calculated level is higher than their **qualified level**, it becomes their new **qualified level**. 5. If in a team, the lowest qualified level among all players will be the 'qualified level' of the team. The team can choose any level below it. Seems all problems solved..." - Neo Lee
