The most entertaining part about RWF is watching people actually care about this guild or that guild like they actually have some stake in it.Blizzard should just leave it and let them bang their heads against it for weeks and weeks instead of just getting more gear.
It is not much of a nerf, the gear they would have got from the vault would have more effect than this.
My thoughts on the nerfs using Delve arguments. "Get better gear, it's suppose to be hard!""Its a skill issue!""Play a different class!""What you wanted this just to be handed to you!""It's meant to last 4 months, not 4hrs!" Personally I say revert the changes and let them live at the venue for 4 months.
