Hobs has hit on it. I've yet to play a game that I've not had to separate what my character is doing mechanically from what they would be doing if I were being true to the character concept I created in my head. Roleplaying isn't about escaping a dull real life, it's like acting in a movie and getting into the depth of a designed character. The props used for the set can either be cardboard cutouts from a middle school play or they can be an intricately designed Hollywood set. Roleplaying is an entirely social aspect of the game and builds strong communities. Someone with an imagination doesn't need props. You could RP in DCUO if you really wanted to, but it's not as much fun as it was in SWG.
RP is a time filler for when you can't do anything else and I'd argue it's the only reason besides being Star Wars that SWG lasted as long as it did.
Will I play this game without tools that support RP, probably. I enjoy pvp immensely so yeah I'll be pvping with Pax. It'll get pretty old fast for anyone but someone who concentrates solely on pvp without some tools. I've gotten use to games not supporting RP and I've gotten older and curmudgeon-ey so I don't do it as much as I used to.
The tools I'd like to see at a minimum (the other things that have been mentioned are nice too):
-Variety of clothing/armor with the ability to dye
-At least the ability to use customized emotes.
-Individual housing with furniture.
-Sitting in chairs
Why wouldn't you want to add things to the Skinner box that players come up with themselves to spend time in your game. They're doing the work for you once you build the set.
