My recommendation is to get your AB/WSG marks at 69, and make EOTS your 3rd queue. You will find it harder to do WSG/AB at 70 when the opposition has full S4. Boxers bring a slight advantage to an EOTS game, they are a disadvantage in WSG/AB. IIRC, you get less honor in 60-69 AV than 70 AV so its not worth the time. Just get your AV marks/honor farming at 70.

This is what I did on my warlocks. I regret not maxing out my WSG marks at 69. It is PAINFUL trying to win a WSG at 70 when the opposing team can just run around you.
