Some people like dropdowns some like big fancy guis. The like dropdown folks are going to continue to dislike Rock, and saying they "just need to get used to it" or "dont know what they need" isn't going to change that preference, only to insult them
What i don't understand is why you would move away from a fully functional non intrusive menu system to a fully function completely intrusive system?
I like many started with AgUF, tried pitbull at various stages and switched around a month after its release and have loved it, rock really does make me think about switching back, which is fine, i don't pay cknight anyway so he isn't losing a customer, but such a silly (my opinion) design decision has many people thinking the same i'm sure.
I like being able to see what is happening on my screen when i change things, and i like being able to do make small changes quickly without needing to load (as in fill my screen) up a big ui, then go press the little x in the corner to i can finally get on with playing.
