I think it would be better if you guys separated the comments from the Ticket Changes; that way it's easier to see the comments and not mix it up with the changes.
Anyone wanting a ticket view page with separate comments from the history can edit the template, It's not hard.
This is how Ticket History used to be, but decided it looked cleaner with them together.
It would be easy with a few template changes to separate them, I can do this and add an option to switch between templates like vBulletin does this the classic and 3.0.0 postbit.
