The new UI is either less clicks depending on what you want to do, or equal. We have literally tested and counted this a number of times internally. It is not more clicks. The fact that you don't have to hit an okay button twice, is a huge benefit to the speed of things. The fact that you don't have to wait for a second menu to pop up is a huge buff.
If you want to join a team, chose model, and hit a preset:
Old: Escape -> Play -> Team -> Model -> Okay -> Point Template -> Accept (7 clicks/actions)
New: Escape -> Play -> Team -> Model -> Template Button -> Point Template -> Okay (7 clicks/actions)
If you want to join a team, model, and manually set points:
Old: Escape -> Play -> Team -> Model -> Okay -> Point Select -> Accept (7 clicks/actions)
New: Escape -> Play -> Team -> Model -> Point Select -> Okay (6 clicks/actions)
IF you want to update your build middle of round:
Old: Class Config Hotkey -> Point Template -> Okay (3 clicks/actions)
New: Class Config Hotkey -> Point Template -> Okay (3 clicks/actions)
If you want to update your model:
Old: Escape -> Play - > Model -> Okay (4 clicks)
New: Class Config Hotkey -> Model -> Okay (3 clicks)
If you wanted to chose a hilt, you still have to hit the hilt button in both menus, except depending on order of operations, you didn't have to hit the first okay button making it equal or shorter.
The only action that can be longer depending on how you do things, is updating RGB color after you are already in the round playing. If you do it before the round it is one less click. A very minor inconvenience for something that shouldn't be changing anywhere near as much as anything else.
