If you're on the fence already, I'd just wait for full release.

-There is lots of PVE
-There is LOTS of building too
-Yes, you can basically not worry about building if you want...
-...for the trade-off that progress is gonna be SLOW and PAINFUL and LIMITED by not building.
-ZERO "character build" options; there is a "tech tree" of sorts where you find better materials over time; use those better materials or stay home. Those are basically THE options.
-There ARE dungeons, BUT...
-...They are all the same and provide no unique "loot". They are all just avenues to more/better crafting materials.

Hope it helps.
