'Most other days' titanic arena would most likely be just as full.
i don't think so...i generally log in at 6:30 central every week day and there are usually more people online in all the arenas m,w,th,f than there are on tuesdays...whether that's because the bars aren't running specials or tuesdays are family nights for the squeakers...i don't know but, try tracking it yourself.
prime time tomorrow night you will see somewhere in the neighborhood of 325-375 in tt...the rest of the week days there will be 225-260 in each lw arena with another 60-75 total scattered in the other arenas.
i just checked lwoh and there were 126 on it...
