"-There will be times when voice chat will be mandatory for things like instanced raids.

-In particular, there is a fear that female gamers will get harassed when the say something and will then want to stay away.

-A gap will appear between those that have/don’t have a mic."

Thing is about this is that these 3 are not prevented at all except for those who never ever raid/do extremes, there are party finder groups that will boot you if you dont use a voice program and some raids are labeled as voice mandatory by groups of players, and female gamers still get harassed on pick up groups using voice programs.

so technically the cons vs pros is actually 2 against 2.

So many games have voice nowadays and games in the past have had voice already, if those gamers survived the oh so horrible cons of voice chat in gaming Im pretty sure modern day gamers will survive as well.
