Please help me with my Mesmer
get inspiration and run the heal signet you should be just fine. I did the whole hot pve in zerker build gs/staff no problem at all.
I myself run almost exactly what you are running except I have ascended armor and use Sunrise and Bolt with a shield. I don’t have problems staying alive. I use the healing and cleanse mantras as staples in my builds along with blink for mobility. I don’t like the heal sig, I would rather have the instant spike healing of the mantra, which can be traited out to give 3 heals which can be used in succession for a huge heal. Become best friends with sword 2, f4, shield 4 and dodge. The more mobile you are the more likely you will stay alive.
