Improved Shadow Bolt didn't increase shadow damage, it increased Shadow Bolt damage and put a debuff on the opponent that increased your critical strike chance by 5% on that particular target for 30 seconds. . . Did you play a warlock in TBC?
It was easily the best DPS spec in the game (or, failing that, the best burst specialization). I've seen 13.5k Shadow Bolt criticals in a video.
