when are minions in instances coming?

[Toodles]

Eh it's about visual fidelity also... making the untargetable only does so little, they still ruin your view & would kill immersion (my little plushie teddy bear is out while I'm destroying Bahamut!).

And a tank glamored as a Snowman or in a bikini tanking Bahamut would not kill immersion?

Fair point, but I would argue this one extra thing would be going too far (as if bikini snowmen weren't already :P).

Especially because often not everyone is a Bikini-clad Snowman... you'd like much more commonly have a greater number of players with their Minions out.
