Best parts of 4.1 for me are Raid Roulette and Beast Tribes.
All that XP for my few remaining DPS classes is just phenomenal and Raid Roulette also gets my Wonder Tails done so much quicker since before I typically avoided the CT raids for lack of motivation.

Royal City is alright, I guess, albeit a bit trying on the nerves when you watch half the alliance crushed under towers or some such nonsense for the 10th time.
Shitryu can crawl back into the aether it came from. I'd like to see add phase but god if I can even see Diamond Dust before any PF I've been in ends up wiping and that was only when I was healing; if I DPS or Tank, we barely make it past 1st Hellfire/Judgement Bolt.
Haven't touched Squardons since I severely outlevel everything they can do that I don't see the point in it. I'll just continue sending them out as glorified retainers that bring me scrips if it's all the same to everyone.
