New Inhib and Nexus tower complaints

Since its still in Beta Riot please change the new inhib and nexus towers. They are way to weak. It seems in every game if you lose a team fight and the other team has enough people to push, they win. The towers don't kill anything. They have a hard time killing just caster minions. The other team easily kills them all and wins. Please just change them back to what they were originally or, make them something different but stronger.
