The point of my posts wasn't solely to prevent leeching - it was to improve the user experience. I read previous posts in this thread complaining about people thread crapping by being negative and not suggesting positive ways to improve the game. My point would even apply to pub grifts, and it's not solely about leeching - it's about getting matched in a group at your level with ease, because at the end of the day you join a clan, some people go inactive, you try to find another active clan, same thing - some people play seasons, some don't, and at the end of the day not everyone is lucky enough to form part of a consistently active clan. I don't know if all of what I just said is on everyone who isn't in an active clan - my idea is just to make the user experience better (the leeching bit was a bonus). Having said all this, I'll drop that subject here permanently now.
On your wizard - last season I did a firebird build but like you I thought it was way too boring to dot and teleport around. I'm having a much better time with tal rasha. That set, with an ancient aether walker, is one of the better rushing wizard builds. That changes if you want to push high grifts, but at least with season 3 wizards got a chance for more burst and less dancing around.
Barbs are still in a good place and are honestly insane in the sense that they were (are?) at the top of solo grift progression, and the idea that they were low on single target dps was laughable if you compared it to even a well geared FB wiz then. Not sure about whirlwind barbs yet.
On your WD - focus and restraint does apply to fetish army as long as you use the appropriate primary/spender to activate the buff. I saw a video from Shinobi on the poison dart pet build and it looked insane - grouped with such a WD and the single target dps was astounding.
I think this patch added a lot for a number of classes - if wizard stays as it is in the next patch (meaning some tal rasha build will be the max grift progression) I'll probably roll a WD.
