You'd be right if that were my point. After quite a few unsuccessful tries, I finally was able to form a PF group for Ravana EX a couple of weeks back and clear it from my quest log. My point is this might not have been nearly as difficult if people who are so adamant about blocking new players (or, more often than not, players who've learned the fight but can't get over the hump) were equally enthusiastic about joining clear/learning PF groups--and, to be fair, I must credit the OP for following this example.
