Well the whole point in doing M+ is time all keys to get KSM at least. You can look at KSM or KSH if you want to see the numbers too, or the KSC title. And then there’s of course filling your vault with all 8 keys.
I’m either tired and misunderstanding or this sounds nonsensical to me. I mean I ‘guess’ you can pug CE maybe but how many complete the raid in full or just invite someone to do the last boss. And how many even pay for the carry for CE? Probably a very very tiny percent right?
