I think the biggest things Ive seen playing the WB are:
Rangers cant stand from 1800 and pew pew anymore without consequences
Thieves cant gank and then try to run away now without consequences
A WB can easily take down another WB (50/50)
Ele is still broken
I would also like to point out that the video(s) in question from DarkFlopy are more about superior gameplay and terrain abuse than anything else. Bravo to you my good sir!
