I wouldn't mind seeing a flag over one's head to indicate one's presence as a RP'er. Just seeing the "RP" over a toon's head would let me know how to approach that person--if to even approach them at all. Sure, you can do that now just by R-clicking on them and selecting "Info" to read the bio; I've found that generally speaking, non-RP'ers don't have bios. But I digress...
I have other concerns, but I've addressed them in another thread & they can't be helped by IG tools anyway. 
They were supposed to have origin specific costumes, and a long time ago origin specific weaknesses (Back in the days when there were things like Gadgeteers), but all of that was thrown out of the window to get the game out to its fans so it could be built upon later.
I'd expect origin specific missions to come in at some point, I'd say after CoV and after all of the game balancing they're doing on the popular powersets.
What kinds of tools to people use to roleplay online? Are there certain tricks that people often find themselves using? What kinds of additional things would help people RP online better?
I know personally, I would love to see:
<ul type="square"> [*] Costumes and name changes to support secret identities. Allow a player to set aside one of their costume slots to serve as a secret identity and have their displayed name change along with the costume.[*] Have better storylines to support characters of different origins. Currently, characters start with different contacts based on their origin and starting location, but once they complete the first few missions, the set of available missions becomes the same for everyone. The new Kheldians seem to have some missions that are specific to them, and I would love to see all the origins have similar specific story lines.[*] Origin specific costume parts. Wouldn't it be great to be able to have a unique suit of power armor if you were a Technology hero? Or a cool aura if you were a mutant or science hero? Just having something unique that you could build into your background to support the character would be a great addition.[*] Weaknesses. Every superhero has a weakness of some kind. It might be nice to be able to get an advantage in one area of the game in exchange for having a weakness in another. Flaws like this are the basis of many super hero stories.[/list]
Just a few ideas that I had... Any other things people might like to see added to the game to better support roleplaying?
