And, to be honest, the rules of English grammar are obscenely complicated to begin with

In relation to what? Mandarin or Tamil? Every language that isn't your native tongue seems complicated. In fact your own seems complicated if you actually think about it too hard. It's a lot like playing NightFire on the PS2 or typing this message, if I actually think about each keystroke and button press I'd never get anywhere. Languages have to be some what complicated based on the complexity of what they are created for and the length of time for which they are used.
