Discord or other voice chat?
 

Is discord the way to go now? I see a lot of guilds use it for raids and such so is that the best or most popular? I used Ventrilio for Dark Age of Camelot and WoW years ago and then the basic Xbox service for like call of duty and battlefield with friends. Do people actively chat or is it for mainly raids and use the old school typing (the horror!) to chat in groups?
Does it run well in the background of EQ? Or can you use your cell phone? I have a second computer so would use it through there I guess.

Yeah discord is 100% the way to go. It has a LITTLE bit of a learning curve, but it's truly the best option out there right now.
