You cited a blue’s thread title. This is what the blue actually said:
Of this paragraph, it’s quite clear this decision is about everybody. Not just about the raiders. Progression is not just limited to the raid, as I mention above. The world content, which leads into visions scenario running is just as important as raiding throughout this tier. Not to mention the fact that new content also means M+, pvp, etc.
To blame just the raiders when there’s only mention of one actual raiding aspect, that being people still pushing their achievements in EP (which is a minor aspect of this at best) is nonsensical.
