Was looking at the new models for warcraft reforged and got really jealous. I guess if there's a time to update those models would be in shadowlands. The necro lords area is probably all about them. One can hope...
They really should just allow a sort of “tame undead” for DKs to replace certain minions with the appearance of others.
“Do not lose time on daily trivialities. Do not dwell on petty detail. For all of these things melt away and drift apart within the obscure traffic of time. Live well and live broadly. You are alive and living now. Now is the envy of all of the dead.” ~ Emily3, World of Tomorrow
Customization would be amazing. Personally, I would game xmog armor for my pet as well, but that's just me. Not a fan of any of them now, all pretty dated.
