Yes they are squishy. However there are alot of slows + vault to help out. You'll end up kiting alot and dropping traps if your damage isn't high enough. Also, you can vault out of the Jailer affixed mob's snare. The goat men attack really slow so it's pretty easy to shoot and kite. Also, despite you not being there yet at later acts you'll probably want more vitality/defensive stats than just pure dex/damage. I had some trouble getting 1-2 shot by Belial and certain elites until then. GL
