Here's a message to all players struggling to reach level 30.
Level 30 is MUCH easier than lvl 1-30, there is no real balancing at lvl 1-30 due to it balancing based on levels.
This means you fight players well above your skill level and must keep doing so until you hit 30. Once you do after a short period of losses or wins you'll be fighting at where you were placed.
Also, don't be afraid of Ranked games, this is more so the case there. The balancing in Ranked is better than normals and you get the same level of tryhards. (I find normals worse tbh) so don't be afraid to jump right into Ranked rather than generating ladder anxiety before you even start.
You will quickly be placed where you belong no matter how bad you are (there are people there with you), have a measuring stick for where you're at and be able to use it to track your progress. A good way to go about learning from there is by playing your weakest champs/positions and learn new champions so you don't carry yourself too high with one champion. In this way you work your way up in a more natural manner without falling back down and also prevent ladder anxiety.
Inb4 downvotes but it's the truth.
