You didn’t actually read what I said, did you?
I specifically pointed to how, even at the times where it wasn’t the top performing choice, it still saw decent representation, sometimes even surpassing both other hunter specs, despite how 1 of them was capable of more throughput.
SoO in MoP is one such example, where BM was managing higher numbers, yet more people still stuck to SV. Another good example is the early parts of WoD, post the initial spike, it traded places with MM in terms of performance for the fights of Highmaul. In general, it fell somewhat behind in certain areas during early BRF progression, yet, it still kept up with the representation/numbers.
You then have Cataclysm’s first half, despite an early adjustment to its performance, it competed in terms of representation with the other specs, until DS where it climbed even further.
In WotLK, it wasn’t really ahead in terms of performance for most of that expansion, especially later on in ICC. Still, again, it saw good numbers in terms of representation. And if currently WotLK:Classic is any indication, this is even moreso the case now, where the representation of SV far exceeds both other hunter specs, despite how MM is slightly ahead much of the time, and has been so since late Naxx(talking performance again).
Not really no. There are some barriers on that end, sure. But generally speaking, if a spec performs well, and people really want to play it, they will do what’s required to be able to do so. The requirement of getting a decent weapon is no exception.
