I am also talking as someone that does a lot of soloing. If you go in this game as a group the VR content is trivial. A group of +4 can do all delves, world bossess and dolmens in less than 2 hours that is about 1/2 of a rank and it is the thing that actually involves mandatory killing of stuff. Grouping for quest is a little more problematic but can be done. I think most people that got to VR10 after the first week did it with a fast group steamrolling everything.
My point is not that VR is great or that it couldn't be done much better. (even though I enjoy it). What I want to say that it is a a manageable grind and It isn't as unrewarding as some people make it out to be.
