I think this type of system should be considered for higher priority. WoW needs something like this… it’s needed something like this for a long, long time.
I found that post very insightful and there’s a lot of great suggestions there, beyond just the key highlights of WoW’s encounter design and the impact on groups who require additional accessibility functions. However, given the Blue response to this, I think this one is maybe flying under the radar a little bit and should be given further consideration. The importance of the ability to communicate effectively with your team in the presence of language barriers or lack of access to voice communications should not be downplayed here.
Perhaps instead of the entire feature being deferred, an iterative approach could be useful? Having access to simple functions such as “move here” and “watch out” on a 3D ping system would go a long way towards enabling groups. Even just those two would be a great addition and more functionality can be added later.
