Blizzard is getting a 70% increase in base damage when patch 4.1 hits, assuming this makes it through the testing process unscathed.Perhaps this is part of the class designers' stated desire to make AoE a little more relevant, and frankly it's a pretty good start.Combustion is, perhaps more than any other ability in the game, completely dependent upon precise timing (and, of course, dumb luck. Thanks, random number generator!) It often needs to be cast at a moment's notice, during a very short window of maximum potential, and removing the global cooldown from it is a needed change. This allows the spell to be cast without regard for altering your rotation, and it can now more easily be written into macros.
