1) Completely agree with. Once the first 8 weeks are over, raids should just be farmable. not 8 months later when everyone is bored of the content.
Are people seriously going to get pissy after 8 weeks if people are able to just replay the same raid to gear up!?

2) Substats are skewed towards damage, things like Tenacity and Piety are completely worthless outside of very niche uses.
Either nerf the hell out of crit, det and DH or just flat out remove them all.

3) YES. Remember when Relic quests gave you GEAR!? Damn, Eureka was a good time, when doing something OTHER THAN RAIDING, rewarded you with raid tier gear.
We arent even getting a Eureka/Bozja style content this expansion, so there is literally nothing new to do once you get the rewards from criterions.

4) Accs should be 1 book, Head/Gloves/Boots should be 2, Legs/Chest/Wep should be 4.
I got super unlucky this tier playing a healer, and ended up gearing my RANGEPHYS more than my main job due to drops and BiS gear.

It took 7 weeks to even get a piece of gear for healer, and it felt like shit.
