gear grind
I don’t think there’s a big need to really “grind” exotics; what you really want to grind is the gold to buy them since most are usually 1 or 2 gold (if that, depending on stats) on the TP. Legendaries seem to be what you want to grind, and those are from dungeon crawls and being lucky I think and are also sold on the TP for much higher prices.
Ascended gear, I don’t know. I think those will be dungeon grinds since they are drops and fairly, new I’m sure the prices are insanely high. Running jumps (as far as I know) are only involved in jumping puzzles. Vista’s are like mini versions be very rarely require you to run and jump and often have easy paths to them if you can find them.
I would suggest reading the blog post about Infusions (here: https://www.guildwars2.com/en/news/linsey-murdock-unveils-new-high-end-ascended-gear/ ). I personally haven’t had a chance to play since all this launched, but hopefully that helped a little bit and I’m sure others can/will go more in depth on the things that I wasn’t so helpful with.
thanks for info.
