I agree about knowing how to play Roland. I have played them all but am a Roland fan. I think he's as good a shot as Mordecai, I haven't noticed a big difference. A lot of it depends on the guns too, there are some outrageous sniper rifles out there BUT there are some equally good sighted combat rifles that Roland does just fine with, he can still pick a bandit off a catwalk above. I find I am using his turret even more (if that's even possible) with DLC4 when those claptrapified bandits rush me. When I play co op I use Roland and my b/f plays Brick and we are almost unstoppable as a team, but when I play by myself, Roland is still awesomely awesome, solo!
I noticed a few of you quoting some of the characters. I have been extracting the sound files from the game and have Lilith, Brick, Mordecai, Roland, Scooter, Tannis, Krom and a few others converted to mp3. The thread is here:
