I dont know if this goes under client discussion but here it goes.
As a silver player, I dont know every spell, every champ has. Especially when somebody is playing something that isnt standards. It would be good idea to add spells to loading screen so players could read (and learn) descriptions of spells your opponents have.
As a pure esports game, it is essential to educate players on champions.
Because without this, I find my self often TABing out and searching for champ in my lane to read what's his spells are and how they work.
