if you don’t complete this key in time it’s gone thats the problem, lol. i queue for a 19/20 and players want to have a player who already did it or preferably already did a 21. and i totally understand why, they want to minimize the chance key gets depleted.
i already wrote all this here M+ Keystones obsolete system
if you would be able freely to choose the key and play it, i wouldn’t write anything on this forum. my only problem is the gating which is created by the keys.
i was playing +12 dudes wrote to me this now i have only 19 sanguine left and will play 20 keys (if i can get into some lol), the real thing that gates me is the queue/keys available. after i will cap on my skill and have no problems with that. but all this time i was capped mostly by the queue. sorry what i have analytical skills and can see the bottleneck.
