I have to say, the current game environment is really making this game unfun. You need to have a mainstay healer (Soraka, Janna, and to a lesser extent Alistar) on your team because if you don't and your opponent does, you've got a tremendous uphill battle ahead of you. And it gets even worse if they're supported by the DPS/heal champs like Ez and Nid. Finish it off with some strong push champs, like Ashe who can volley your team at a tower safely out of range, and it just gets ridiculous. Their team stays out of range and heals up any damage while you get continually harassed and can't do any damage. Repeat until they can just rush the tower and knock it down.
