Dragon Buff

The new dragon buff is cool and all but the 5th time a team kills the dragon kind of tilts the game to one side a little too much. What im thinking is, the better team ( probably with more kills) will most likely have more control over the dragon ( being the dominant team). So by the fifth time the better team kills the drag it becomes way to one sided and the teams ( from what I've seen ) are able to push almost all the way through with just that one buff, its worst that the buff is infinite as well, so now that the losing team has barely survived a raid from the opposing team with dragon buff, but they have to do it all over since the buff is not lost. I'm not saying remove it, but nerf it ever so slightly.
