I just want to comment because lately i have been getting a lot of complaining over Rammus. First of all I usually play Dominon with Blitz, or Pantheon, Ryze. Lately I have been trying out other champions for the simple fact that I own them and would like to play them everyone once in a while even if the may seem "OP".
Well last night I was playing and in the opposition was a Gangplank that kept auto-attacking killing himself in the process. In our first encounter he mindless beat me to death after I had previously exhausted my shield. During rez, I chose to purchase Thornmail because I figured it would help me if I encountered him or any of the other AD's running around. I might I add that right after I was easily CC'd by Ryze who continued to completely crush me.
My point is that Rammus is not unbeatable, I had trouble with Ryze and even Akali, which at times I simply ran away from. But for GP to mindless auto attack me and then complain about his OPness is just unwarranted. Items are there for you to purchase and counter your opposition with.
