I ask these 4-5 questions every time someone asks me this, or every time I notice a friend is tilted as fucked with ranked
1-Do you want to be a streamer?
2-Do you want to be a youtube content maker?
3-Do you want to compete in tornamants and win some money?
4-Do you have some big dreams of joining the LCS one day? (i will never laugh at anyone who tells me they are serious about this)
5-Do you want to become stronger, and face stronger opponents? (the competitive fighter spirit)
For the only way you can experience ANY of these things is if you are at least gold. I have never heard of a youtuber or streamer become famous who was lower than Gold. The only exception I can name is ross boom socks, but he climbed to gold so he isn't even silver anymore. If you want public respect you need to at least be gold to earn public respect. For options 1-2 you can get by just fine if you are funny, but that is only if you are very funny and consistant. But for options 3-5 you can only experience this if you do ranked and improve constantly.
If you have no desire to do any of these 5 things, excluding getting a free skin once every year (often they suck). their is zero point, or reason to do ranked. If you lack fire and ambition to become a stronger player, than all you are doing is wasting the time of your teamates in ranked, who most likely do want the five things I stated.
Nothing is wrong with doing normals though, enjoy the game, have fun with it.
