I know there are multiple ways to go about dungeons and it's completely viable to exclude Mesmers and Guardians and still easily clear a dungeon.
With the obligatory disclaimer out of the way:
I'm relatively new to dungeon-running and the playing Guardian class and want to know what cookie-cutter abilities am I "supposed" to use when paired up with Mesmers (or anybody for that matter) in dungeons.
Right now I'm running a 0/0/30/30/10 build which is pretty close to the majority of PvE tanky builds I've seen looking at various videos and guides. I use Knight equipment with soldier runes. My weapons are greatsword and hammer.
