The only actual complaints I have about the new hud

1. Sort of non-descript. Not easy to immediately adapt to, takes more than a couple of games to find everything (especially if you havent seen the official hud reveal Riot sent out a little while ago)
2. A little bit too clustered. A little bit of spacing would make it better. (Less spacing than the old, more spacing than current)
3. The level indicators aren't very.... indicative? Putting some dots under the abilities doesn't feel like it shows much. If you want to keep the circles/dots, maybe you should stylize it a little better? Bring back the old hud rank indicator and mix it with the new one. Voila.
4. why is the tab screen so much smaller? It's kind of unnecessary, considering you're the one who's bringing it up on the screen when you're not in the middle of a fight. Should be bigger and less clustered (like point #2)

All in all, I do very much appreciate the style of the new hud, but it's definitely not finished. Has readability issues and isn't the easiest to figure out what's where. (I dont know if it's better or worse for new players, either)
