The only way I can see debuffs are if I look at the target that has me targeted. I see buffs just fine above the shields. Others have told me they see their portrait above where your team you are teamed with is listed. Why would you not be able to see your portrait in space like you can on the ground?
Just an example I seem to remember you could change what instance you were in in space but I cannot find how to do that now. I think I remember doing it in Beta by right clicking the portrait.
