I would rather game some kind of in game event on the Holodeck.
I hate going on Test servers, I would rather wait for the new content to go live, not get forced to go on Tribble just to get an in game reward that will be on the C-sore in a month.
That's not what I pay my sub for.
The option should be there for the people who enjoy that kind of thing and have the time.
I got the Tribble of Borg but I'm not going to go on this time, I would rather CP did there own testing and gives us a real live event, something that we have yet to get.
You do realize the entire purpose of the 'event' is to get a good cross section of players to test the nerw Update prior to pushing it to the Holodeck server, so it has less bugs when it goes Live. They want more people BRCAUSE they realize their internal testing doesn't catch everything; and they don't have the amount of sheer hardware diversity in their test lab to catch all the hardware issues that might exist in the new build.
No one is making you do anything on the Tribble Test server either. If you don't like going on there, that's entirely your choice, and it's perfectly valid/okay.
I do agree though, it would be nice if we could get some interactive GM events run on the Live servers from time to time; (and I think there have been a few 'PvP with the Devs' events, but I agree, that an occasional live server event like the end of beta 'Borg invasion' would be nice once in a while.
