So here we are , im gonna attempt to explain why the mythic plus system is flawed right now.
so in order to progress you need to start doing 9+ to get gilded crests. all good till here.
Then in order to max out vault you need to do 10+ . here starts the first big issue , the increase in difficulty is massive, so people are less inclined to invite you . not only they are looking for people that have timed a 10+ but also overgear the content. Keep in mind that people who have gear are the ones that alraedy did 9 and 10 and above. so you cant really access that difficulty because of the problem that is about to be explained.
m+ pushing for the vast majority of people ends realistically at 11+ . So you have only 2 keylevels worth of pushing till you hit your big seasonal wall which is 12+ and above.
basically the whole mythic plus experience starts around 9 + where you need the currency and ilvl drops + vault and ends 2 key levels above that which is 11+ .
i think for player retention, keeping people interested and plain enjoying the game this is a very very problematic thing. My season ended effectively after i timed all 11+ just because the 12+ is such a steep difficulty increase that pugs will NOT take you unless you are some superfotm class or geared to the teeth.
Why do we get only 2 key levels worth of endgame content till we cannot progress anymore?
not only that but also at this moment there is a HUGE pool of players stuck inbetween 9 and 11 . and this will only get bigger. no wonder why you will never get accepted in LFG . with you there are a ton of people wanting to get in just because the ones that should have moved on to another key level ( like 12 and 13 and so goes on ) cant because of how insanely hard it is to 1) get into a 12+ 2) time it
