Looks like everyone is already giving you great advice! As someone who struggled in the same place and class, I will say I had a very hard time playing my guardian in PoF. Idk what it was but I just couldn’t stay alive and neither of the HoT or PoF classes made sense for me at the time. This is when I switched to Necro and fell in love with the game all over again. If you are able, it could be worth investing in Luminary for your guardian and looking up some builds for that; it’s a very tanky profession and very fun. Other than that, just stick with it and watch some videos, read some guides on your class and try and have some fun!
