Every meta is different. In my local meta, few players bother with playing the latest meta-list and those that do usually only end up winning a single event. It's not that they get bullied, intimidated or get the stink eye until they get in line. It's nothing like that.
It's simply that when a player (especially a new one), brings a meta list and manages to win, the more experienced of us recognize it, strategize around it and by the next event, we figured out the counters and our local meta changed in a single leap. We plan with the meta in mind, but we usually don't play it because those that do can often start at a disadvantage. Weird, huh?
