If Relic wanted to impress me, they would create a moddable UI API kind of like World of Warcraft or similar games in which you can mod/change the UI (even Dota 2 has this even if its somewhat limited)
I would rather they copy the UI from COH 1 or COH 2 and just abandon whatever the hell this trash is that they are trying to make that isn't working.
Idk man, I'd say we should at least try and give it a shot for a couple weeks and then determine how good or bad it is.
I still remember very well: When I started playing CoH2 in 2013 after 4 years of CoH1, I absolutely disliked the new UI and was like "omg this looks so shit, CoH1 UI is much better" but after a couple weeks I loved it
