I was musing about Personal Loot a bit more, and began to wonder if Personal Loot would fall out of favor with guilds when Nighthold is released.
A somewhat unique element of the raids released so far is that there have been no tier sets released. The first Legion tier set is coming in Nighthold.
At that point, though, guilds may feel that guaranteeing X set tokens for the raid each week through Master Loot is better than leaving set bonuses up to random chance. Sure, on an individual level you may have to wait, but eventually it will be your turn.
I'm also watching The Old Republic's new loot system, where all loot, including set pieces, comes in a random lootbox. It does feels like the the largest complaint against the system is the possibility of getting very unlucky and never getting your set bonuses.
Well, the SWTOR community doesn't like the system as a whole, but I think that the set pieces are the single biggest complaint. I wonder if Bioware could mitigate a lot of the complaints simply by having set tokens drop from a few raid bosses, even with leaving set pieces dropping from the lootbox as well.
It will be interesting to see if Nighthold does change the dynamic, and push organized raids back towards Master Loot.
