I am not sure if it's a good or bad thing, but after a few days of retesting WoD Apexis Rares procs (I did test 200 kills with only a few terts and no sockets / wf at the end of DF), I can confirm we can now get every slot in the game with a socket. Terts are still possible (they never left), and the broken "Warforged" title proc is back on the menu, even tho it provides no stats difference at all and is just visual.
The new BiS farming meta for F2Ps would be:
0. Complete all (~10) socketed items quests for an extremely low chance of an extremely small stats upgrade.
1. Get all your main set items from TBC (go for tert / socket procs if you desire) and neck from DF rares (once per day)
2. Try your luck on all relevant BFA rares (one time per char, you can check more
HERE),
3. Return to
WoD Apexis rares* for a once-per-day chance of a socket proc on whatever slot you still have missing.
Str/Agi Cloak, Int 1h / Oh, Shield, Ranged weapons and Trinkets are the main things worth considering in steps 2 and 3.
I will soon update the guide to include this newly confirmed change. Happy farming!
*There are some rares that are repeatable but not shown in the spreadsheet by
@CigNus. The easiest way for me to figure this out is to use
THIS addon and look for the purple sculls on the map (the white ones are once-per-char kills that can only proc epic ilvl89 but no tert/socket has been ever confirmed)
