One of the best quality of life changes LOL ever made was....
There was a time when the only colors used on champ health bars were only blue and red. Your champ health bar was not color coded to differentiate you from your team. Your health bar was blue along with your team. The only way to keep track of your champs was to actually look at the champ on screen.
I can't count the number of times I lost track of my champ during a team fight because of this. Many times running into the fray as a squishy mage when I had just started playing.
When they changed it so that your champ health bar was yellow and not blue like everyone on your team, it made a big difference in my gaming life.
It's a simple change that went unnoticed but made a huge difference.
I just wanted to point that out cause I have nothing else to do with my life. Have a good day.
