This wasn't my decision, it was vova2112's.
No. The interface is very clunky and unattractive. The bar seems to be a compensator, a monstrous intestine. It needs to be even longer, lol. The combat buttons are at the bottom and top of the screen. Everything is scattered in different corners; you could twist your neck and dislocate your wrist if you don't use the hotkeys.
Well, you see, it's a matter of personal preference. I'm not bothered by it at all, and in fact, I'm happy to use "W, C, Space," and I don't need any more buttons on a regular basis.
I like that the buttons on the side take up little screen space.
And I also find the long bar convenient, on my monitor.
