Guild Wars 2

I am sure the 70%+ will say Warrior and Elementalist asap. And its true, but i am wondering what other classes might be extremely useful.

I am not sure if this should be a discussion about them, more like i wish to hear opinions on this topic to shed me some light.
I dont generally like PvE in Gw2, but i started doing some dungeons, like Ac P1-2 Story, Cm p1, and TA story, and seen some stuff i rarely see usefull generallym so i decided to roll a class that might be fun to play in pve, since its usefull.

I alredy have Ele and Warrior (by the way…and its boring to play them generally)
I seen some really nice Guardians, are they fun to play ? Viable? Are they wanted in LFG?

Guardians are viable yes, they have been a top tier class in all of gw2 for as long as I can remember, fun is subjective; I think they are ok, but that’s me. Are they wanted? Yes of course they are, they are extremely useful, can do some high dps and massively pug friendly.

Warrior, ele, guard, thief, ranger and mesmer are all incredibly useful in dungeons. Engi is a good pug class due to its wide range of utility. Necro is just bad because its so selfish. So essentially 6/8 classes are very good in dungeons. Engi is ok and necro is bad. Ranger has some problems, mainly due to the sword auto attack but if you can work around that its a very strong class when played right. Mesmer is kind of a niche use class in speedruns and only worth taking if portal can be used to speed things up. But its a good utility class for casual runs providing a lot of reflection coverage, condi cleanse and control.
