So, it's not like the Hydras need +500 vs Armored to be effective, maybe they even don't need any bonus at all, or a very low one.
I don't think that the Hydralisks were designed as counters to Siege Tanks, anyways. In BW, they're next to useless vs them.
With the modification, they would be twice as hard to kill for the Roaches, and that would change the balance quite a lot. But really, i don't think that it's even necessary to modify the Hydralisk's armor Type.
