Is not a factor for people doing WSG as a premade currently. The rank cap is currently rank 3, which can be done getting ~2k honor in a week at R0(which can be done in about 3 wins in WSG while not farming HKs), then 4.5k in a week at R2 to hit R3 on reset(for me, this was about 2 hours with an LFG chat group, with no gear/consumable requirements and the closest to an “optimal” comp was having one priest).
People queuing in premades are primarily queuing to grind rep from revered to exalted in WSG. They’re playing capture the flag - which is what WSG is - not blobbing in the middle. Now, if you want to say cut the rep by 3/4 and give 4x rep… I mean, if people are going to play like the BGs I experienced yesterday morning, getting 25% rep while forming a trade/lfg chat group and actually playing the battlefield objective would probably end up getting you through a rep grind faster than solo queue giving 16x the rep when this is what people are doing when solo queuing:
