And I don't think anyone misses TB. WG battles on the other hand were amazing. They required coordination comparable to a normal mode raid spread across a vast amount of space with every single place mattering. No BG comes close to how WG was especially when both sides were balanced (which CRZ can do). It's just about adding rewards to make sure more people queue though with CRZ that might not even be a problem.
You also don't have to thumb it down right now because it isn't a bg and you have to queue for it separately (so don't like it? don't queue for it).
