Seeing more and more spirit weapons in spvp.
It’s fun, yes.
In group fights, you might even enjoy seeing your hammer smash people around on occasion. But eventually you will realise they die too fast, their special moves often miss and two of them don’t really do anything worthwhile.
You’ll run into classes that easily counter your spirits weapons by having them slowly attack some worthless minion or smash the ground they used to be. You’ll die, you’ll be angry at your shiny weapons and wonder if it’s you, or if they’re just letting you down.
Finally, you’ll look at other guardian builds and realise that spirits weapons in PvP is crap. Fun, but crap. You’ll discover meditations, a line of utility that doesn’t suck in PvP and become a monster that all classes but engineers should fear.
You’ll never use spirit weapons again.
So in short, no, they’e not viable if you want to do good in PvP.
I found the hammer was only worthwhile spirit weapon in sPvP. However, that was back when they were invulnerable, now that they can die, they’re dead (heh heh) to me.
