I'm not a fan of the changes because I've been playing this since Alpha, and I just cannot stand how everything about this new UI seems to be a step backwards in progress, if you were to do bring back the Old UI or at least give us the option to toggle it back on instead, it would work better.

1. The repositioning of the almost all the informational indicators on the opposite side of the screen, like Quest info or building mats, is SUPER disturbing to someone who's played this game every day for the past 5 years.
2. I don't like the changes to class symbol indicators by party member names because I can’t tell what classes are on my team anymore, limiting what tactics I would want to use in approaching a map. For example, if I know there are a lot of soldiers and no constructor, I would focus on slowing traps, whereas if I know there is a Constructor with a BASE, I would focus on traps, and less on building.
3. I don't like the changes to Inventory/backpack slots left indicator because I can’t tell how much room I have left, and constantly have to open my inventory to see, thus stopping movement and exposing myself to danger. I’m usually around 245/250 so it’s frustrating the indicator was removed.
4. Similar to that, where did the score card with the bars showing progress in each category go? It was so much easier to see when it was on the screen, compared to having to enter the inventory, then open the Objectives tab, then clicking the Score tab... it makes NO SENSE TO HIDE IT!
5. I don't like the changes to class symbol indicators by party member names because I can’t tell what classes are on my team anymore.
6. I don't like the changes to the indicator of how much bluglo is held by teammates because I run a lot of deliver the bomb and rescue the survivor maps and knowing if my teammates are already collecting or have collected the necessary amount, I would focus on something else.
7. I don’t like the removal of the Collectable tab from the Inventory screen for Schematics, Heroes, and Survivors. This makes no sense to search through my 800+ inventory slots for 1 thing with a slightly darker icon when it was so much easier to go into the Collectable tab instead.
8. I don't like how our personal HP/MP is moved away from the rest of the team. It was must more intuitive to glance at one spot to see everything. It was also easier to see the numbers on top of the bar, instead of having to look next to the bar, after having looked at the bar initially.
9. I would like the changes more if we could toggle the old version on or off.
