So, I've got two fun examples of this.
First off, the valid example. My team just got destroyed, down to inhibs and behind against a team that had a much better team fight potential. I'm playing Sion, I'm not exactly doing to well. But I've got a bright idea, using his passive and his ult. If you know the current meta, it should be obvious, but this was like a year ago, so it wasn't "THE META". I figure that I'm a big dumb tank they need to kill twice, and my ult allows me to crash into their mid inhib turret and beat on it forcing them to deal with me. That's exactly what happens. My suicides into their tower destroys it, and their mid inhib is now completely open. I'm serving as this annoying distraction as the rest of the team defends and slowly but surely catches up. They've caught on to me, and now travel as a pack down mid, with only one or two missing at a time. I use this to my advantage, ult into them, and if I hit, I flash forward dragging myself to their inhib. If I don't hit any of them, I hit the inhib and drag them back. I do this a few times, and the inhib falls. My team has caught up, and can now fight decently enough that they win fights as I keep assaulting them with my want to die. Turns out, that effort actually won us the game.
The second example was an AURF game, so it's not entirely valid, but the core is. I got heim, and well, I know how to heim. The games pretty even, they've started winning the team fights though, and they are down to their nexus turrets, but have quickly pushed us back to our own through team fights being lost and them getting good picks. So we are in the final legs of the game, a few teamfights have us on the defensive. That is, until they go to baron. My team goes to defend, and fight for it, but I decide that no matter who wins, the game is ending, and use that chance to sneak through their jungle and flash into their base to avoid vision as long as I can. The fight is going on, and if any of them back they lose baron. I throw down turrets and my ult turret, and take two towers as the fight finishes. If I remember right, they won but are down by a decent amount of people, and their jax backs to stop me. It's too late, the distraction paid off and I've won the game for my team.
Point of the both examples, is that in low elos, distractions can do wonders. Doesn't matter if you are just buying time, or actually making an effort to push and you just so happen to draw their ire. A good enough one, repeated or not, can win the game for your team if you are behind. It's not going to be easy, and depending on how good the distraction is and if it can be constantly done, it may not be enough. But it's a strategy that is pretty common, and is part of the reason Inting Sion and Trynda are so damn good. Not only are they good distractions that can soak up damage, but they require at least a few people to fully stop because they have a quirk that is difficult to put down solo, Trynd's ulti and Sion's immunity to the first death cc applied to him mean that you need a decent amount of CC or insane burst to put an end to them.
