A Few Suggestions

First:
I think it would be a lot easier and cleaner if all the 'PvP' style maps had a seperatee tab from that of the Challenges. It would just make it easier to navigate through all the challenges, and if you are looking for a PvP map the tab is right there as well.

Second:
Its been stated a few times, but the ability to select certain stats that could be used to filter if an item shows up as a green dot or not. It could be as simple as "look for the stats which you have actually put your level up points into as top priority." It could also be as complicated as being able to open up a menu and select which stats you want it to actively search for.

Third:
This one is pretty minor, and I should have said it a long time ago. I think if you "block" with your weapon you should not get webbed. It could help alleviate a lot of bad situations, as if you get webbed you could potentially sit there blocking until you find a good opening. I feel immunity to web in bloodrage / CtA would be a bit too much, but then of course the Barb has web immunity sooooo who knows.

----If i think of some of the others I will update..but right now I am dead tired so I am off to sleep

I agree with the first two, third, dunno.
