Carrying as an AP mid
Can anyone tell me what I can do when it comes to carrying as an AP mid like Syndra. I can crush lane and then go roam and and help get kills and take things like dragon, but my teams never push towers to end the game and it always results in us losing. I can't really push on my own/split push since my aa do little damage and if I'm caught alone I can get killed easily. So, even if I crush lane and we have a kill lead we still throw in the end. It's usually around the 30 min mark when my teams would stop taking objectives and would just farm for whatever reason. When sieging as a team I know you need to ward around your area and behind so you don't get flanked. Any tips? Do I perhaps need to try shotcalling, am I missing something that really important, or should I just stay away from ap mids for the time being when it comes to trying to carry.
I've mained ADC for a long time, but I've gotten tired of it and I decided to learn and main mid to climb in s5. The transition may be what's messing up my games, but I'm not sure.
