affliction league mechanics

It's so laggy when I go in the other realm that the color trails are almost invisible. On the rare occasion that I find a vendor (because it's mostly the side areas and boss encounters) I have to recheck the areas I've already revealed because it's so dark. There have been more than 10 times when I go past a vendor or two because I don't have enough random crystal things of the right color to buy anything and then I run out of reveal juice only to have the portal spawn on top of me or the enemies I was fighting and before it's visible I get ported out and get nothing for my troubles.

The league mechanic is so rewarding, and could be really fun. I have made more currency this league than any other and I haven't even come out of yellow maps yet, and the trans skills are pretty interesting and strong. Why is it so buggy and hard to interact with. I want to like it, and I'd like to skip it while it's hard to deal with, but it's so damn rewarding.

and it turns off the map overlay, which is annoying as all get out!
