It's certainly not terrible; it could be improved though. I think a good idea to combat the long scrolling for larger messages would be too compact the messages at so many characters and then when touched reveal the message in full. Several phone apps I have utilized have this feature to compact conversations that are too large or span many lines.

The translation feature was a great idea. It really expands the possibilities of speaking to people of different languages in the clan chat. Hopefully they take into account the censoring issues as well, since those seem to be causing people some grievances. All in all not as bad a system as I thought it would be.
