Sure, it's also a plus that I've found perfect examples of all-out rigging, but the real reason why it was a good thing to do is that I can show that during my climb from Silver 2 to Gold with Nunu I was:
- Second highest damage to enemy champions 1 time
- Third highest damage to enemy champions 3 times
- Fourth damage to enemy champions 8 times
- Lowest damage to enemy champions 23 times
I've sometimes used Thunderlord (not for itself but for +5% cooldown reduction) with full ability power build and sometimes Bond of Stone with full tank build. As I had to select the masteries and runes before the game started, it's clear that I knew in advance what build will work. Why? Because I know how the matchmaker rigs. If it gave me a "Sure Loss", I went with full tank and enganged the enemy early to force teamfights instead of peaceful lane game where the carefully selected enemy carrier could feed on our selected feeder. In teamfights our OKish team beaten the buyers+boosters enemy, my job was only to engage first and take the ulties of the buyers who just couldn't resist focusing the nearest red, even if he had Spirit Visage, Thornmail and Warmog. When the game was easy win, I just disappeared in the jungle and fed on monsters building a magic damage glass cannon. When teamfighting phase naturally arrived, I was 2-3 levels over the enemy jungler who wasted his time ganking, my ultimate damaged over 1500, my snowball damaged nearly 400 magic and we had 3-5 dragon advantage thanks to my busy soloing. In fair games I picked the second strategy, simply because I liked it better, sometimes worked, sometimes not.
If I played every game with Thunderlord-glass cannon, I'd lost 80% of the Bond of Stone games, keeping me below 50% winrate. If I played every game with Bond of Stone tank and early engage, I'd lost most of the Thunderlord games as good players simply ignored the unkillable but zero damage Nunu. The trick was that I knew in advance what kind of game will come since I understand how the matchmaking works.
The players with the high damage defeated the opposing players in one game. I, with my #4-#5 damage defeated the system in most games. Needless to stay that focusing my energy to increase my play would have much worse returns than analyzing the system. This is why I don't even bother to argue with "skillz" players, I simply moderate them out. Poor things are not even wrong, they simply stuck on a simple understanding of the game and unable to contribute to any meaningful discussion. Don't be like them! Understand the system and beat the system if you want to climb high. Or show everyone how it's broken and have a high traffic blog!
