Towers painfully too weak

Push wave in 2-3 times, by the time you're back from your first or second back you're strong enough to push in and take first tower. Even a solo laner like Renekton can just shove in all lane and just wait for you to back so he can just burst the tower down. When I play with a duo in bot we always get first tower. Always. We joke about it at this point. "We'll get first tower and our team will find a way to throw the lead". So although first tower doesnt mean "GG", it just allows people to group sooner than I believe to be necessary. Sometimes I'm even hesitant to get first tower because I don't want to have to over extend to keep farming lol.
