My experience at identifying contradictions from forum posters is vast.
By your own account, you have proven that you don’t NEED it… you just want it, despite already being successful without it.
None of this matters though, because it’s likely that the only way it’s ever coming back is if Blizzard bean counters believe that having it return would be a net gain to revenue. Since this issue only affects a very small amount of players, I would not gamble on that happening.
If it DOES come back, then the Blizzard of recent years will be likely to monkey with it (as they tend to do).
At the least, they would probably decrease drop rates in ML dungeons to make it just as effective (time-wise) to use either method. Or they could get weird and put in something to protect recruits… like keeping recruits on PL for 60 days after joining the guild.
The possible iteration possibilities boggle the mind.
