I agree. So far I've only really played with my friend -- sometimes in person, others on third-party voice chat -- and some of the plays we've made would've been nigh impossible without prior communication. I think it's a bit odd that there is no in-game solution for multiplayer communication. We have a textbox for the combat log, and Larians has implemented something like this before. Emotes would be fun too -- I loved using the emote system in WoW back when I played it.
I'm sure some people will be nasty and say mean things in chat, but that comes with the territory (the internet). It's a blemish worth accepting for the good that comes with it, imo. It would make playing in a random group a lot easier. And I for one would love to be able to uninstall Discord -- getting people onto my mumble server for a game is going to be too many hoops for most people to jump through.
If patch 8 is going to be the last hurrah, as it were, then an in-game textchat doesn't appear to be in the cards, unfortunately.
