Dear Darkstar,
I very much welcome this change to the LG contribution screen. However, I have 1 thing to say. This change basically cuts the time in half compared to the old screen because you don't have to click on the "+" button anymore. Look at my picture at the bottom of this post. I currently have a level 63 arc and plan to bring it all the way to 80. If you look at rank 1, he spends 1995 forge points. With the old system it takes forever but with the new system you still have to press 199 times on the "10 FP" button in order to put in 1990 Forge Points. Clicking 199 times is a large amount of clicks, it gets tedious and annoying because people with 90% arcs often spend 5-10k FP a day. Sure, this change cuts the time in half but there are a lot of good options in order to lessen the time it takes to spend a large amount of FP.
The best option would be a window where you can just enter the amount of FP you want to spend. I understand that this is currently not possible due to technical limitations.
A realistic option would be to add a 50 FP button or some other number that is higher than 10. Let's just take 50 as an example. It would take 5 of your 10 FP packages so there is no need to introduce a new 50 FP package. My proposed change would SIGNIFICANTLY reduce the time it takes in order to spend a large amount of forge points.
If that is also not possible, what exactly will you do or have you done to reduce the amount of time it takes to invest a huge amount of forge points? You have removed the + button but that's all you have done so far. There are so many different ways you can improve the player experience for high Arc players but it is sad to see that nothing major has changed.
I am scared that you'll just leave it as it is now, roll it out to live servers and never change it again.
