You are all so negative. I loved how the year began with the second coming of Revan! B) Mirror matches might not be fun, I agree on that. But at least it made f2p players (especially from guilds who can't do hstr yet) who focused on him and well-modded Jedi around him, able to compete with the high end of the arena shards for a while, including the whales.
As for the droid rework, I can't believe how many people really believed in the hype that it could become the next meta. I learned from Cad Bane's rework to never expect too much, and was pretty sure from the beginning that Grievous is only distraction - still as viable as a common legendary though, while the next real meta will definitely be Sith again. And don't forget, when you watch youtube videos made by the game changers, they are not only advertising the game, but also themselves. Some of them are quite enjoyable, but with childish claims like "I will delete my youtube channel bla bla", that one youtuber you know who I mean, actually provoked the overhype and deserved to fall for the trick. I rather watch videos that focus on content and real theory crafting, not showmanship.
