This thread will compile all of the unnecessary punctuation in BoL, hopefully for its removal. I will make a new post when I find something that I think should be changed.
Sources of excess punctuation: - Global Messages - "You Won" After defeating a monster - "You Lost the Fight" After losing to a monster - Experience gain while tradeskilling - "You found x source of Y" messages while battling/tradeskilling (I would assume this also applies to finding items, but I am unsure at this point)
Additionally, the side interface that tracks when you find items, resources, or you increase a skill is inconsistent in punctuation. Increasing a stat will have an exclamation point, but other messages will not have punctuation.
