Am I the only one annoyed by the fact you can't see each others skills? (Or damage)

I liked being able to see other player's skills and I think there were times were seeing people's skills are actually helpful. A good example is when fighting Vellum. I can DoT him with inferno and then my party can see him when he hides underground.

Do you not see other player's damage and skills just at boss runs or is it like that all the time now?

Only at boss runs.
I trained with a party at HoH on 2x last night, and boy could I see everyone's skills and damage.

At boss runs the main problem is that the damage numbers cover the boss (or the whole screen if there are summons), and you can't see its buffs or debuffs. In extreme situations you can't even see the boss itself.
