Returning Mesmer
The builds on metabattle are typically instanced PvE (dungeon/fractals or raids) and are not nearly as good in open world PvE.
In open-world PvE, you probably want one ranged weapon on top of the sword-shield, typically GS. Then, shatters will indeed be a larger part of your damage in most (short) fights, especially with chronophantasma allowing you to shatter once without loosing the phantasms. You will start to want keeping your phantasms alive if you expect the fight to last at least 10-20s.
For the utilities, you don’t need the wells and the alacrity nearly as much when playing solo, so I usually go for at least blink and usually decoy as a good way to avoid getting aggro.
This will increase your survivability a lot.
