Runway in use

Flew yesterday online for the first time in a long time. As I departed there was ATC at my destination (EIDW)

As I got closer ATC logged off, no problem. (No ATIS)

Wind was 180 @ 11 ( not 100% sure of the speed but sure of the direction)

EIDW has 10L/28R, 10R/28L and 16/34. Now 16/34 isn't used unless it's crazy windy.

Today 10 was the best runway given the winds.....

There were about 5 aircraft ahead of me and two behind, all following the STAR for 10L as I became number 5, someone decided to depart 28L....... Then when I became number 2 another 28L departure ????

I get when it's very quiet, you could sneak out to the closest runway rather then a long taxi but when there's clearly a good few aircraft using 10 why would you depart 28 ???

Is it just me ???
