Distance to target and AoE indicators would be infinitely helpful. For those who don't want to use them, put it on /toggle. Let the rest of us enjoy the convenience.

Information display is a good thing. Knowing the range of an AoE or distance to target doesn't make any combat inherently easier, it just allows people to more accurately use their skills. Arguably, it allows people to play more skillfully as they can focus less on estimating distance/AoE range and more on using their skills properly in combat.

Just because people got on without it before doesn't mean we shouldn't have it now. Have you ever heard of innovation?
