Hi my name in LOL is Entrecampos and I'm only a Bronze III because I'm a player with some health problems (a difficult Tremble in the hands, I have a problem similar to Parkinson). I'm a much better play in games like Hearthstone and slow pace games, where I reached 369 Legend in Hearthstone at my peak. Altought I reached a low level with my limitations in League, I think that Sona is very overpowered, with a good win rate and an easy gameplay (except for ultimate that is hard to me to use). I think that this guide can be good(only) for players that want to win games and climb in Iron/Bronze to Silver Direction. Low level players need to understand that what can be good in high elo, can be horrible in low elo players. And the opposite is also true. I think that one of the big problems are rage and thinking that we are better than we really are. The others in our team are bad, I'm good, and the other team is feeded only cause the feed of my team. This is a bad view of the game in my perspective. I have a 3.54 KDA with Sona in Solo Queue, 2.6K/5.3D/16.2A, 65% win rate, and I think that I can reach and climb to Silver with this champion. I started Iron 1 some days ago, and I made 34 games this season with Sona, won 22 and lost 12. Knowing your limitations is the key to improve and reach a better ELO, is in your errors that you can improve more to be a good player in general. It's more important to be good in all, than be pro in some factors and horrible in the others. I'm trying this, and I understand that will be impossible for me to be Gold, I'm very bad farmer, in all real time mechanics, and reactions movements. I like to be support and help the team, not being toxic, trying to help them to don't be also, and I think that it's the best position for me.
I will update and expand that guide later with my future experience. Please don't criticize me because I'm a bad player only, but try to help me to find better builds and sugestions to this guide and try new alternatives in my case.
Nobody is the perfect player, only some are better than anothers. Try to remember that always.
Thank you for your attention.

After 2 days, I won the promotions to Bronze II and reached the promotions to Bronze I. I upped the KDA from 3.54 to 3.94, now I have 2.86K/4.86D/16.27 instead of 2.6/5.3/16.2. I upped the Win Rate from 65% to 67%. As you can see in OP.gg, https://euw.op.gg/summoner/userName=entrecampos I will update the guide now.
