On the party screen add a button 'skills'. When pressed, a pop up window shows the skill bars of every party member.
This would make planning so much easier. It would also add strategy to the random party PvP. It would let you know if that monk is a healer or a smiter for example. It would also help with discussions as to what to bring on a certain outing.
Can't really think of a downside.

There's an easier solution to this. Ask them what skills they are using, for PvP or PvE, most organized groups use a VOIP. (VOIP is Voice over IP.) Essentially a program you can use to talk to other people via a microphone. Such as TeamSpeak and Ventrilo, aswell as Skype. They all come in handy for such events.

I don't see this as being a solution. Even if the random group you are thrown together with has teamspeak going, having each person read off their 8 skills is certainly not as good as having all of them pop up at once. I'd say it would take a very well organized group to make your method work. The random arenas would be much more strategic if you could tell the capabilities of your groupmates at the touch of a button.
