Now I'll start this by saying I have no problems with the new targeting mode system and I play all classes. Having said that, I think the system could easily use a few luxury improvements. Things we could honestly live without but things that would make certain functions more convenient.
1. Distance to Target. In Aion there was an option to turn on Distance to Target which would, as the name implies, tell you how far you were (in meters) from a target once selected. This was especially helpful for Rangers and mages who had skills that were only effective at specific ranges or had minimum ranges. These ranges were put into the tooltips for most skills.
This is by no means dumbing down the game, it is simply making some things more convenient. I can't tell you how annoying it is trying to use a throwing weapon only to see "The target is too far away." and having to inch forward only to see it again.
2. Variable targeting icon. Supplemental to, or in place of the above suggestion having the targeting icon change to designate in range, out of range, etc... would be infinitely useful as well. Again admittedly a luxury function but a convenient one.
3. AoE Range. Please give us some way to determine the range of certain AoE skills easily. This isn't a problem with some actions but with things like Arrow Helix and Iron Tempest, it's hard to find reason to use them since their range seems so ridiculous.
I'd suggest two different ways to fix this:
1. Show a translucent colored mark on the ground for the radius of any AoE action. Some kind of UI indication of where this action is going to hit would help things greatly. It would make things a great deal more convenient especially for mages and Marauder.
2. List the AoE range in the tooltip. Along with the Distance to Target, knowing the range of the AoE action would be incredibly useful.
Again I know these things are simply luxury features and not of high priority however I'd like the team to consider them at some point in the future. These are not features that would be dumbing down the game. There is a difference between convenience and frustratingly difficult.
