I think when they said that LUA will be moddable, but they are only allowing UI mods though. I will try and find it.

But graphical mods aren't good for an MMO game. People can easily cheat in the game if you allow it. So that's why I believe they are going for UI mods only.

Nah dont bother yourself with it, I dont care really.

1: Agree completely.
2: If they're able to do it in a good way then yes.
3: Why not
4: YES! I hate the token system, sure it's "fair" but it makes dungeon/raid-going a lot less exciting
5: Nah, companions should be acquired in forms of other players.
6: Yeah.
7: Yes, I think the Dark Anchors are one example of this.

I think they'd all add (aside from 5, don't see the point in an mmo, in my opinion) to the game, however I would be willing to sacrifice dye for having a armor appearance tab as well as the actual equipped armor tab so you could change how you look but keep the stats of the good gear

LUA is a scripting language. You can't use it to implement what you're talking about.

I absolutely detest dye's. They never look right. Color is changed too much by the texture overlay due to how mapping works.
