display primary profession only?

If all the skills on your skillbar belong to your primary profession, how do I remove the secondary profession (or have it display only my primary profession)? I'm on PVP. Thanks.

So you mean like, if your char is named "Bob Smith", you're an Elementalist primary with a Monk secondary, you want it to just say "E20 Bob Smith" instead of "E/Mo20 Bob Smith" when someone clicks on you?
As far as I know, that isn't possible. As soon as you choose a secondary profession, you must have a secondary displayed; "none" isn't an option.

IF you dont pick a secondary you can show only your primary--for pvp, (in pve in order to progress thru the storylines your are forced to pick one *--there is one way around this for nightfall characters).

so the only way to not have a secondary on a pvp character is never to have picked one in the first place. (so re-roll and you wont have it).
