most PvP is in a team with at least 3-4 ppl right next to you. Plus at a 50m range, they don't really need much resist cuz they have a 30m escape just in case. You won't find yourself in many 1 vs 1 situations because most rangers just sit behind the rest of their team.
Very true! Unless you're in Strongest then your team in nowhere to be seen lmao. I have 18m escape, rarely use it as I find even that is too far to dash back. When (if) I level I need to lose more skill points in it anyways, prob down to 10m, or not take it at all.
At my level I have 38m range without Fixed Firing, and 46m with it - I find it's plenty for supporting from behind my team's lines, but if I get stranded the extra 16m I have over casters isn't enough to kill any casters really before I get squooshed by 1-2-1 bolt -_-e

Then again my ranger doesn't have amazing gear so meh I probably deserve the roasting.
The biggest reason IMO rangers seem so overpowered in PvP is because people seem to stack up resistance and not defence... and as the OP said, there's a lack of Long Range Defence buffs to compensate.
At the end of the day it's pretty futile hoping classes in this game will ever be balanced, we have to deal with what we've got
