Well that's sort of my point. You shouldn't be wiping 10 times in Tionese or a Tionese with some Columi mix. I have actually not run the flashpoint so I can't speak to it's difficulty, but I have seen people recommending a full columi geared group at MINIMUM, which is just screwed up as far as I'm concerned. If you are going to make a flashpoint that you need to be that geared then I would assume more than one boss will drop a Rakata (even if it is just implant/relic/ear).
Again, you don't NEED to be geared, but if you aren't then it will be much more difficult. I don't know why people expect to just go in and kill everything without even trying.
