This is probably not much of a problem for most players but I just want to say.
Some characters don't display in the legion comm. I know in some games, especially MMO ones, typing conventions can actually evolve together with the game.

On the other hand, I could imagine giving lots of limitations to the in-game communication channels resulting in a distinctive minimalist/nonchalant/impersonal conversations (^-^); - like robots!

Well i dont know about that. But the Legion Com Chat Buffer needs to be extended some or at the very least give you pages to catch up on then when your done reading them you can hit the x button and kill the page from your feed.

With the way some people talk, you can miss a lot, and sometimes important information from the staff, cause people yakkity yak too much.

At the very least 2-3 extra pages worth in the buffer would be nice.
