Guild Wars 2

So i’ve just came back to GW2, took a break right after the expansion came out and now I feel like trying this game again.
I’ve noticed there are changes in PvP with the expansion bringing new types of builds and i’ve looked up a few, so far I’ve found that MetaBattle has the most recent updated ones and tried the most popular ones, even checked out a few videos on Youtube to see how to use these new builds properly and this is where I guess my rust kicks in.
I’ve always been about a decent PvP player and I don’t think i’m that bad but so far the few builds I’ve tried for some reason don’t work for me, either I don’t do the amount of damage the build claims it can do or last as long as the build claims it can do so I was wondering if anyone knows of any other pages with more detailed info on how to use the builds or perhaps videos that show what to do cause these last 4 rounds of PvP I ran a tanky Guardian build and I still got slaughtered, the most I held out was like 10 seconds and that was with healing and all the boons I could muster.
Thanks in advance for any help!

If you play a guardian and die in 10 seconds there’s something “wrong” with your playstyle. isn’t a big problem, you just need practice, nothing more :-)

The actual meta is fast and dps oriented, then make practice isn’t always easy. I also tried the Dragonhunter and died a lot before be able to inflict good damage and survive to a fight.

Chose your class and try to ask in that forum section for a help, someone will explain you how to use it.

Anyway, the practice is your best friend.
