I just resubbed aswell a few weeks ago and decided to cap my warrior who had been my main for the previous 10 years, and I've had a lot of fun on it.
I've enjoyed Fury a whole lot, and once you get caught up on some gear there's not a lot of things holding you back in terms of like Argus WQs and stuff.
Prot seems like it's still prot and I've always enjoyed it.
I'm yet to play Arms this expansion but I look forward to trying it out.
I always have a hard time choosing mains when a new xpac arrives, often leveling a new class almost straight away after I capped my first choice.
But this time I feel like Warrior is once again my lovely main.
