You know that raiderio will show you exactly how many keys players within a given bracket have completed yes? A quick glance will tell you all you need to know. Do you honestly think that there is an actual tangible difference between a 14 and a 15? This is a serious question. If someone is capable of doing a 14, they are easily capable of a 15. Especially in the current season.
There are people who purchase KSM carries, yes. I have yet to group with a single one of these in any group I’ve been in. If you’re making the claim that someone managed to get carried in random groups all the way to KSM…I’m sorry. I don’t believe that one.
A five doesn’t have complete mechanics and affixes, so this is intellectually dishonest. I stand by my claim. If you can do mechanics in a 10, you can do them in a 24. Once you hit a certain level, everything becomes a scaling issue. When you’re able to effectively handle mechanics in M+, all you need is the group composition and the gear level appropriate to the key you’re doing.
A key not depleting is not the same thing as a key advancing should you fail the dungeon. I’m fine with people failing. I fail. I do not agree with the key regressing upon failure however. There’s no reason a 15 should not be a 15 unless the player holding the key decides it should be lower. There are far too many variables at play to make key depletion anything other than a completely bad system design.
