What stats for my Shatter Build?
Pretty sure berserkers is the go to for shatter builds, power/precision/critical damage.
I agree with WillOfIron, shatter build you just need to jump around a lot and do a lot of damage. Osicat, see his forum post in the following link , https://forum-en.gw2archive.eu/forum/professions/mesmer/guide-WvWvW-Shatter-cat/first , runs a shatter build I use and explains it all. Also Amayasu, Parthis on the forums, runs a 20/20/0/0/30 build and uses full berserker.
Ok, you think not taking any toughness is worth it? I use my mesmer for WvW, not for PvE
