People suck and they get what they deserve. Good on SE for pulling their finger out and doing something for a change.
Also, screw master levels. Does anyone seriously enjoy having to grind that much?
Hardcore mmo players love progression systems, it's a foundation of the genre and one of the reasons people keep playing. The only thing worse than a long grind, is having nothing left to progress on your fav job.
Asking a hardcore (and we mostly all hardcore here compared to most other mmorpg communities) if they like grind is like asking someone really into fitness if they really love working out, they kind of do but it's really the results they like/want.
When I capped job points on my blue I was happy for a few days, and still liked being capped but I was also sad I could no longer make anymore progression on my fav job. I like Mlevel even if I never cap them, because the mindset of knowing I still have stuff to work on is a positive.
Also Mlevel isn't anywhere near as important as Job Points, so it's not required to cap them.
