problem for real via client-side patch
They're well aware of what the root causes of the problem are, it's just not something they can address via hotfix. The honor boost is/was an obvious band-aid fix until they can address the problem for real via client-side patch.
They thought that the consequences of ludicrous honor gain would not be as bad as the old state of the zone where World of Warcraft(EUR) it wasn't worth bothering to attack. They have since decided that they were wrong and they'd rather see the zone be hard to flip than have it be win traded for several times more honor/hour than any other activity in the game, hence today's hotfix.
