Recommend a build
Since you don’t care for PvP or WvW, I’m assuming you want something for PvE? Are we talking dungeons, raids, fractals, open world, or all/any of the above?
The short answer is…You’re in luck!
In fact, the only commonly viable mesmer PvE builds are support-oriented; designed to drastically boost the abilities of your teammates. Not so lucky on lockdown though, that’s not a thing in PvE at all, not even a little bit.
I was thinking raids, but I still need the gear a just general familiarity with the skills. So for now dungeons and fractals, later – raids.
