Honestly I’m down for small frequent updates with the big ones being paced out 4-6 months apart.
And by small I mean things like the human / Orc heritage armors. Or even the small bits of customization coming like the zandalari hair colors. Those bits are nice when we get them every couple months or so vs having to wait 2+ years just for an expansion release for them to be a part of.
Imagine they have a small enough team that is able to focus on a specific race every few months, that frequent additional customization will put a lot of people happy imo and it would allow them to focus well too, for example they could focus on BE jewelry for BE next round, then do another category for BE the next time. Akin to how it’s zandalari hair colors only this time around.
