I asked several players why they queue for RBG without really knowing the mode or objectives, and 99% of the responses were that they just want to hit 1.6 rating to get the tier token. (Seen people just going afk, going to inactive camp, or geniuelly avoiding any fights.)
In my opinion, they should either remove the token from PvP rating altogether, or raise the threshold to 1.8 or 2k, OR make the token earned from PvP rating exclusive to PvP gear. Currently, you can use the same token to buy either PvE or PvP tier sets, which contributes to the problem.
As it stands, people are queuing just for the reward rather than to engage with the mode properly, and this will likely continue unless changes are made.
