Guild Wars 2

I’m having a very hard time soloing it , I’m playing with cleric guardian and I can’t find enough players to do it with me.
What is the best time (GMT) to play with as many players as possible ?

I suggest you guest to the higher population servers. They seem to have substantial number of players around the clock.

I’m in Gandara server which has the highest population along with other ones such as underworld and desolation.
I did most its achievements by chosing the right time to do it which was around 8 pm GMT.

I would try immediately after reset if possible. Usually there is at least one daily that involves the tower or the enemies that are only in the tower.

Tarnished Coast had overflow servers last night from reset till about 11 eastern fwiw.

I think for most EU servers the fact that the reset is in the middle of the night, which is usually one of the quietest times, counteracts any boost in player numbers.

If I remember correctly Gandara is, along with Desolation, the main UK server, which means peak times will be evenings and weekends GMT. I’d say try from about 6pm – midnight, or mid-afternoon onwards on weekends.
