About the new UI
Just some thoughts of the UI change as a person who has played this game for a long time and lacks the time to play that much nowdays. So, as a person with little time to play it takes me basicly longer to adjust to new things. New champion every now and then, some buffs, nerfs, remakes on old champs is something you just need to get used to and I have nothing against those. But this UI change made it allmost like a new game and not in a good way. It feels allmost like an unwriten rule of games that score is shown in the top side of your screen and team in the side. This way it is easier to get used to a new game. What you did was fuck this order up. Now when I try to look at my cs numbers or my team HP/ulti I end up looking around my screen for so long that a soraka could assasinate me. And with the time I have to play it is going to take months to get used to this unlogical change.
The character stats(ap/ad, armor, mr, etc) was something that I also liked to keep track of a little more and the change of color when I had something more than the base ammount was awesome. It kind of filtered out the numbers I don't need to focus on. Putting all the stats(pene etc added) in the smaller box is good but put the 2 sections side to side and visible all the time (via checkbox in settings is ok if others don't want them to be there).
Then the cooldown showing on abilities. It's shit. Why change the whole coloring and picture and everything on the icon of the ability when it goes on cd and make a cooldown clock that isn't visible. Old one where off cd part of the pie was just the ability icon and on cd part was shadowed or darkened on that icon if you know what im meaning with this. That was clear and could be seen with a glance.
The icons for your teammates are too small and in the wrong spot. Also having the enemy team deathtimers above your own team is confusing. It's nice to have them but you don't want to mix your own team with the enemy team.
When you level up it's hard to notice. I don't personally keep track of my exp that much and when I level up there is no clear visible indication. I think there used to be a beam or a glow on your champ when you level up but now it's just ability leveling options sneaking up there. I'd rather keep watching my positioning than my abilities.
Not really UI change but changing the color of red side minions to red made things alot more clear to me. As colorblind, for me purple and blue are the same and changing to red there is a difference in the minion color. Thanks for that
Next time you go and change thing around try not to press the randomise button and actually think what you are about to do.
