Guild Wars 2

So I am building a collection of ascended trinkets (back item, amulet, 2x accessories and 2x attuned and infused rings) for future use and I am trying to think of how many sets I should have, and what they should be. I have one of every class and am inclined to keep it that way for a while.

Of course, some sets are more useful that others, and bank space does not allow me, for example to have 3-5x berserker, or every possible stat in my collection.

I have, so far, in no particular order of importance or usefulness:
1) Berserker (multiples, actually)
2) Sinister
3) Viper
4) Knight
5) Cavalier
6) Soldier
7) Apothecary
8) Selectable (not yet “locked in”)

I also have partial sets:
9) Cleric
10) Captain
11) Celestial

Which other sets do you think are useful/popular enough to add to my collection? A few come to mind, but I would like to read what others think.

Hmmm… it really depends on what game modes you play, but I notice you’re missing boon duration stuff. I’d say Minstrel’s (chrono tank, healer/boon ele, etc.), Marauder’s (helpful for power builds in wvw, mixing and matching), and Magi’s (healer druid) might be useful.
