Is the effort worth the reward.
I need to collect over 100 Writhing Essence in order to upgrade the two Legendary piece of gear I have. There is a fairly low percentage chance that I will get some drop at the higher 970 level. An even lower chance that I would see the decent items I currently have equipped drop at the higher level. I have 0 desire to participate in Normal or Higher raiding, even less desire to run at least one Mythic + dungeon a week for 20 essence rewarded from the bonus chest on reset day. I could farm the island to receive 1 for every 100 Legionfall resource order placed on the island. That alone would require doing 200 quests on the island which seems a bit extreme. Sending followers out on a 6 day mission rewards 500 Legionfall resources which would convert to just 5 essence. Emissary cache’s reward anywhere from 1 to 7. If you took an average of 4 for a drop rate that would require doing about 13 emissary blocks of 4, but at one emissary a day would take you near 2 weeks to complete just 1 upgrade. So it appears that in order to upgrade my two pieces it will take a combination of many things, and probably a month of time or more. And what would I achieve from it. I am presently around 903 for my item level, doing all that work would be a grand increase of 3 points in iLvL. Certainly I would become a bit more powerful. But I have to ask myself,
And I have to think also. Have I been pushed to far with not only this expansion but with how much we needed to run the final boss in Draenor over and over to upgrade our Ring.
