I've just read that Bioware have nerfed the content in the latest build, so that all Flashpoints between 10-30 don't really need a strict trinity group make up. Do 4 DPS can faceroll their way through the content.
Not to sure about this change. I see why it was done, but it doesn't bode well for player skill on those newer to MMO's at endgame. We all had to learn to tank/heal/manage threat somewhere.
Hopefully, it's just Bioware trying differing things out, as I've heard they've also nerfed back the crafting/modding system, but only to test different ends of the spectrum, so to speak. According to Georg Zoeller, the internal build he's working on is far in advance to whats on the beta servers currently.
