I was ready to join in the ranting about 'the dumbing down of DDO' until you reminded me of this one. >.< Oh man, I hate those rats.....
But that said, it is unfortunate that the OP's playing experience was ruined in this way. It really might be a good idea to check over the wiki or a similar sight to make sure that you know about and are able to get past any puzzles before you get to them. But it seems like most people enjoy the non-hack'n'slash that these puzzles provide.
