Can look at the list of skills on the wiki:Noob question, do they have a spell gem that functions like disintegrate from D3, a continuous death ray you can swerve around? Alternatively, are archers good or shit with these changes?
Skills - Path of Exile Wiki
Blue gems tend to be the "spells" even though there's some spells in other stuff. There isn't really a beam, however for example there's incinerate which projects a flame as long as you hold, and the longer you hold, the stronger the flame. It has more limited range than disintegrate but you can in theory get increased projectile speed gear/support to make it longer range, and you can also use lesser multiple projectile to create 3 flames at once to increase the size of the aoe.
As for archers not sure, don't even know how they are now. They used to be all the rage a while ago but nowadays I think they're just only average. They should still be fine though and they're adding a new archer skill I think in this patch, while buffing bows damage. Checking quickly the ranger forum, a few of the top builds seem to still be archer based with people killing Atziri with them and shit, so viable for sure. Nothing really becomes "unplayable" like most people say, it's just stuff that becomes "balanced" lags behind stuff that becomes the new OP. I guess current OP are spells and low life builds and shit like that but most of it is getting nerfed next patch so meh.
