Sigh

When i first started playing league i was introduced to it by a friend, he taught me the basics of the game and played with me until i was level 30. I was very inexperienced my support play was decent at the time. When i first started trying ranked i was immediately put into silver, my friend who was bronze at time thought that was super cool and wanted to play ranked all the time until we were both silver... as you can expect it didn't go as planned and i ended up falling to bottom of b5. I stayed b5 0lp for quite a while and even had the same friend surpass me and cut me off from playing together. Its not a sad story though because i had learned from a lot of my mistakes and became a better league player. The only problem is,i occasionally get to b1 99 lp and drop to b2 like very often and its frustrating. Personally the problem that i see in my game play is communication between my team and this goes extremely well when i have a friend play adc for me and we can win like five games together and maybe lose one and its a really easy climb but my friends that i duo with are very inconsistent which just makes me kinda tilt and try to solo carry games. It works for some games but a lot of games i just cant connect with teammates and we lose the game. I know i should just be more patient and wait for my friends to have time but its crazy that i get too 99/98 lp bronze one and just go on losing streaks.
