It's mainly because PvP is in a fundamentally broken state and instead of addressing the sheer brokenness of the system, they've just added more gear. (which actually makes the system even MORE broken).

It's sort of like if T6-T9 were completely broken and not fun and nobody wanted to do them, so SE said they'd fix it! Come patch day, they just add a T10 and call it a day, without addressing any of the problems inbetween. It's basically the knowledge that PvP will be completely doomed for at least another two months.
