I might have imagined or I might actually have read (I can't find the source at all, so I'm leaning towards the former option) that WildStar will feature a "fully customizable interface". True or not, such a quote could be interpreted in a few ways. a) Having the ability to move interface elements around as you wish. (Example: Rift, LotRO, EQ2) b) Having the ability to skin the interface. (Example: LotRO, EQ2) c) Having the ability to create interface modifications to help improve your gameplay experience in various ways. (Example: World of Warcraft, EQ2 (to an extent, see ProfitUI), Rift (soon, at least), Warhammer Online) d) Any combination of the above. Another option to consider is macros, which could be thought of as a part of interface customization (due to reducing hotbar clutter), but also as a different beast entirely (not technically interface). World of Warcraft is a good example of how to implement a macro system - it's not a requirement, but will help immensely in performing certain tasks. Rift is a bad example - reducing your entire ability lineup to anything from one to four buttons and being forced to use them if you want to be a top performer. Personally, I'd pick d) and go with all of the above. People have different ideas of how they'd like to have their interface set up, so the ability to put any part of the interface where I want it to be is perfect. Similarly, interface textures are not always to everyone's tastes, so being able to change them, too, is nice. I don't really think this will be much of an issue for me with WildStar, though - I like the UI we've seen through gameplay footage quite a bit, although I guess it is subject to change at this point. Then there's interface modifications. Whether it's letting me display certain stats on-screen without having to open a window that takes up half the screen, or something that will put me on a random mount or pull out a random companion pet when I press a keybinding, I'm good with that. Anything that flat out automates gameplay is a no go, however - the early version of Decursive from WoW springs to mind here, which allowed instant curing of any curable debuff without the player needing to take action at all. There's also grey areas, such as boss mods, which is an issue I'm torn on: on one hand, I find they are extremely useful in learning new encounters, but on the other they are far too often used as a replacement of a person's own ability to observe and react to a situation. This, obviously, is a Very Bad Thing. Now, if you got through that wall of text, let's hear your own opinions on this topic. Also, I know the addon/no addon debate can turn into a heated one, so let's try to keep this about your own personal preferences!
