I only discovered that CoH had returned a couple days ago, so I'm only lvl 24. I'm guessing a lot of people are in the same boat, so there probably isn't a large percentage of the playerbase who've reached 50 yet.
But hopefully that'll change, and raids will be a common occurrence. I organized and led the first successful Hami raid on Victory in early 2005 (and about 100 more each day after that first one), so doing another one now would be quite a nostalgia trip, even if the fight has changed somewhat, and no longer potentially rewards several HOs, and even if the HOs no longer give dual-50% bonuses which can be stacked 6 times. Wow, the game was really broken back then...
