Guild Wars 2

TL;DR: Ranger, Ele, X?
My wife, daughter, and I are forging a group together, and I’d like a little clearer picture on effective metas. For better or worse, 2/3 of the trio are chosen: Ranger and Ele. The third is up to me. I understand that any combo will get the leveling job done, but I am not looking for “any” combo. With Elementalist and Ranger in mind, what is a third member that will round out the group to cover the combo/banes/boons spectrum, allowing for effective dungeon and small group pvp success?

Further explanation of why any given profession is better would be much appreciated.

Ele and ranger are support builds in PvP. What you’d need is a high mobility damage character, something like mesmer, revenant, or thief. I would strongly lean towards thief if the person playing it is pretty good with video games, thief can be difficult to master in PvP.

Dungeons are so easy that it’s irrelevant.

A mesmer or necro would cover boon removal but there isn’t a whole lot of PvE content that requires it. It could be more useful for PvP
