Why all the anger?
I agree that everyone should voice their opinions but come on guys, changes are bound to happen. Everything people complain about makes no sense. You guys shouldn't be freaking out so much about any changes. It just happens, adapt and overcome.
The new HUD is not worth complaining over, I got used to it the day it came out on PBE and I really enjoy it. Yes it is not something that people are used to and yes there should be an option to switch between the two. I play with my HUD scaling size at 33 and can still read the stats and everything perfectly while it seems many others are saying that the numbers are too small. The placement of your teams health-bars just means you shift you eyes down instead of left.
The Fiora VU doesn't look good to me but to somebody else it may look amazing. This is just an opinion thing. There is no reason for everyone to cry about it. If you don't like it, just don't like it. Voice your concerns but don't bash on it. Also saying that it is complete crap will not make them change it, they will just find somebody that does like it and feel happy for changing it.
Just let them do their jobs over at Riot.
