Yea seems like the English community rely a lot of voice chat programs for communication unfortunately. Wasn't much of a problem when I was on Mandragora (JP server) where we rely more on macro to inform party members

There was a pretty epic thread by BamDeafPie on how the community discriminate against deaf players before mods deleted that thread. But you can still look for threads he post, some addresses deaf accessibility.
