"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. Players can choose any GR level **below the highest level he cleared within the past week** (or X days, as Blizzard wishes). Let's call that highest level their '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 enter any level below it. All problems solved." - Neo Lee
