Normals are really, for the most part, to mess around after you hit level 30.. Some people don't like the ranked system, but in reality it's the exact same thing except it tracks your progress, which is why it's so encouraged to win in ranked... People don't care much if they lose in normal because it doesn't cost them anything (such as LP in ranked). Being in competitive play is actually a big deal, for most people at least. It's extremely looked down on if you want to try, say a new champion in ranked. That's what normal are for. Honestly, what's 1 extra loss when your progress isn't being tracked??
Solution: If you think that's a load of crap and you don't want to see "It's just normal," Play ranked. If you think ranked isn't so special, then why are you complaining and not just playing ranked where you literally won't ever see the phrase "Oh, it's just normal/ARAM?"
Normals **is actually **an excuse to play worse. How else would you be able to try new roles or champions?
