I'm saving the hunter perk for last...I just made a hunter ring and swap it in before hitting the shrine and right back off again. Hunter Perk first seems like a waste of a perk when its just as easy to gear swap.
My perk order was Dealer, Treasured, Fortunate, Accomplished, Enshrined, and I'm working my way to Hunter now.
Dealer first because I was always short on coins which hindered my gameplay the first time through.
Treasured next because those Eternal and Crystal items converted to useful crystals and saved a lot of converting to be able to roll the farming gear I wanted and get perfect rolls for stuff.
Fortunate to boost the amount of those drops even more...and by the time I got there, I had capped all my farming stats with farming gear.
Accomplished to then speed up the process of hitting feats, which, with the previous perks, boosted my chances at great loot even more.
Enshrined is great for upping your chances for rare legends and spawning red and purple enemies, but its a lot of work for a guaranteed legend drop from a red enemy and eternal drop from a purple enemy, when they are already so plentiful from my earlier perks so it was low on the priority list.
Hunter last for the reason mentioned at the top of the post.
One other thing that really helped me was, I'd wait until I was really close to the Find Crystal and Find Mythstone feats and then use a legend map. Right before collecting the last crystal or mythstone I'd throw on my crystallized or Mythical gear. Between the legend map and the gear, the crystal and mythstone explosions would be at the highest rarity possible, and I got a bunch of Ruby, Amethyst and Obsidian that way. I'd always wait to convert any Eternal and Crystal gear until I was on a legend map, and make sure I had my crystallized gear on when converting for the highest rarity crystals there too. Finally, whenever I'm on a legend map, I buy all the items in the store, both before and after I kill the cartographer. With Crystallized and Eternalized gear on when you buy from the store, you have a great chance at getting Eternal and Crystal equipment which you can then convert to more crystals.
This really makes crystal farming go smoothly and I've had a really easy time rolling up the gear I want with perfect rolls.
Edit: A few more little tidbits I just remembered...I also do all my crystal salvaging and converting and rolling on legend maps so that the Use Crystal feat happens on the legend map too...same with Mythstones.
I reroll pretty much every map before using it. My goal is to have 2 or 3 beneficial stats (I count pack size as 2 so if the map just has pack size and all the other stats are negative but not on my Do Not Use list, I'll use that map.) My Do Not Use list includes Leech Nerf, Potion Nerf (I can handle a sub 60% potion nerf map if I have pack size) and skyfall. I don't love enemy heal maps, but if I have pack size I can clear those too. I love resists, immunities, speed, attack speed, damage, etc. because those don't really bother me, I use effective and weakened in my build so I tear through the resists and immunities. Point being, rerolling your maps saves you a ton of time, and always shooting for pack size gives you more loot and xp, and if you use a leech build, makes everything easier because you have tons of HP coming in. This all allows me to farm at floor 600 once I hit level 50 during my ascensions so that I'm farming for gear and crystals and leveling at the same time.
Last little tidbit is that I was using my dust to make eternals to convert to crystals on legend maps, but I haven't had to do that for a few ascensions because the crystals have been pretty plentiful.
