I'd love that option so much (and have definitely asked for it somewhere before, just don't know where anymore..maybe the QoL request thread?)
I played Mabinogi for many years, and the lack of chat bubbles here is still so horrible to me because I KNOW how much more social and interactive and lively it makes things >.<
Of course, it should be an option that you can turn on and off, it would be annoying in raid and I'm sure some people wouldn't want it at all, but I am convinced a lot of people would like it :3
