You’re firing off with the assumption (and that’s all it is) that players don’t need valor gear if they don’t intend to raid. That’s incorrect. Many non-raiders do, in fact, want their characters to develop and like the idea that it can happen without grinding the ghetto of LFR or committing to a schedule that someone else dictates to them. This is so that they can quest more easily, complete the solo-scenarios that we’re going to see and enjoy things like rare-hunting or achievement chasing. Presumably we’ll see more scenarios and dungeons throughout the expansion, as well as other content such as the Timeless Isle, and people would like to take part in that, too.
In short, arguing that only raiders need valor gear is incorrect. It may be what you believe, but it’s not reflected in the activity of all players.
Secondly, you’re letting yourself slip by then saying that players who don’t raid are “locked into redundant and finite content”. What makes it redundant? Your opinion? That’s not how it works. In one expansion, a so-called “lol feature” called pet battles has already made itself more popular than organised raiding; substantially so. If there was meaningful dungeon and scenario content throughout the expansion, plus other sources of valor such as the pet battles I’ve mentioned and depending on how garrisons shake out, there’s nothing objectively “redundant” about it.
You don’t like it, and that’s fine. That’s your choice.
But arguing that it’s redundant because of that? Well, that’s
you not making any sense.
