But my rant was triggered by a specific instance of a common, general pattern that I have been observing ever since 4e came out. (I don't really remember it happening in Ye Olde Dayse of 3e.)
That's because, in 3e, the correct answer to "my character is weak against x" was "Play a Cleric or a Druid!"
4e is, generally, really well-balanced, which gives rise to new forms of foolishness as some people try vainly to "break" the system while others try to equate "balanced" with "the best thing since the invention of beef stew!"
