1. Make it so I can see my factionmates as easily as my crewmates.
2. Let me button mash in an advanced combat interface
3. Let me email crewmates with materials and information
4. Put in some scripting language to make plugins.
Sure (4) is the most weird request. I just want the same thing that I have in WoW. Trackers of xp, loot, easy ways to reskin the interface, inventory at a glance, maps of the area I'm in with overlays of things (like bad guys and what they drop). There are a hundred different little UI type changes that I would like, but that's no guarantee that there are others that would like that. So, give me a language to plug in my changes and then if I call and ask for help the first thing tech support says is "Have you turned off your plugins" or "We have a signature to the server saying you are using plugins, we don't support that".
It's not too much to ask. Although, to date, WoW is the only game that has had this kick ass feature.
Oh and speaking of features, blogger arbitrarily cuts off posts after a certain character count is reached (I think it's actually line based). Not cool. Give me a popup saying that this post is longer than X lines and may be truncated. Don't just let the thing post and let me think I'm ok.
