I thought it was fixed. I figured there couldn't be any other possible problem on my end. I launched a Custom Game successfully so I assumed it was all good. I admit it wasn't my best thought out plan, but I'm sick of these problems with the client and their system. Even if I hadn't made this mistake like I did, a lot of people here know that the system will remove LP from you even if it isn't your fault the first time it happens (although I honestly wasn't sure at the time).
To clarify, the first time it happened I didn't notice a penalty to my LP so I though to myself "Oh, I guess the system DOES notice when it's a connection issue and not your fault (at least if it's in the champion select lobby!)" so I didn't think I was at risk of losing anything. But when I tried the second time is when I noticed my LP dropped and I got the dodge time penalty. I never did extensive research on the ranked penalties so I thought I was okay.
I also have responsibilities in my life like everybody else, so I don't have a lot of time to mess around in a normal game and hope it works there, so this is one of the few chances I have in the day to play ranked.
Again, I admit I didn't think this through all the way, but I also didn't have all the information, and I have only certain times during the day that are free.
