Yep, I skip deep desert too - either turtles/trolls or VR for me.
For VR you need to be very careful - they hit far harder than trolls.
For trolls I'd hit one with DPS & then hit it maybe one more time, then switch target to the one beside it and kill that one.
I could just stand there while the first one beat on me and I had no troubles - no chance of getting killed.
That is not
the case in VR. If you try that in VR you will die (unless you have huge defence).
3-4 shots from a boar and I die - sometime 2 shots if I am particularly unlucky with their special attack.
So, I hit them with DPS, VSS, Rapid Shot and then run. And keep running until it dies.
Reload the bow & move on to the next one.
Make sure you register for party search - if you can get a party you will get very rapid XP.
Otherwise it's a slow grind
