OK so legacy loot. As far as I’m aware, when a raid tier is defunct but not added to legacy loot rules, it is actually better the more people you get for the purposes of mogs and mounts etc. Since the raid doesn’t assume you have the max number of players and therefore may not give you any drops at all.
But when legacy loot comes into play, the opposite becomes true. I.e. The less people in the raid, the better for you since the raid now assumes you have a full compliment of players and drops loot accordingly despite maybe only you being solo.
Yes? Ok. Good. Now for the confusing part: Mounts. Some mounts seem to be immune to the aforementioned rules. Like, all the mounts from WoD backwards drop like regular loot. So if you want the maximum chance of getting the mount, the fewer players you run with, the better your chances of you getting it if it drops. BUT, there also seems to be personal loot mount drops. I.e. mounts where, if they drop, the chance of you getting it is the same regardless of how many players are in the group. These mounts automatically get put into bags. There is no actual item you loot. E.g. the one that drops off Mistress Sassz in ToS or Mekka’s GMOD mount in BoD in BfA.
However some mounts that drop in Legion seem to operate the old way. e.g. the one that drops off Argus in ABT appears to drop like regular loot in the loot window.
Now remember, i’m NOT talking about the drop chance. That’s the same regardless. What I am talking about is IF it drops, the chances of you getting it vs someone else in your group. So if you run with 1 other person and a mount drops, you have a 50% chance of getting it. But if you run solo and it drops, you have a 100% chance of getting it.
Am I missing something here?
