Maybe the problem is that GW has failed to take into consideration the pedantic nature of it's player base. I personally believe that the Swarmlord is adequately described as a Hive tyrant in it's description.

Cute dig Alan. But words have meaning and the rules of the game are the rules of the game. Other manufacturers have shown that they can write rules that are clear, and issue timely FAQ when mistakes are made. There is absolutely no excuse for GW publishing rules like spirit leach or not specifying clearly that something counts as a hive tyrant. This is very VERY basic game design.
You can whine all you want about players not playing the way you like... but the rules are abjectly badly written, and some (like spirit leach) are abjectly unclear or have unclear interactions with other rules. Of course we can 'house rule' them. But that is no excuse for GW dropping the ball.
If GW doesn't want to support players using the rules they should stop writing codexes and just make models for us to use under whatever rules we feel like that day.
