Because I'm not denying that skill isn't a factor, but most times it feels like that the RNG dominates this whole gamemode. First we have the item RNG, then we have the champion RNG, and then we also have the match RNG. The last one is basically the outcome of a fight if nothing is changed. Sometimes I got matched with the same composition multiple times in a row and nothing was changed, but the outcome of each fight really differed. Not to mention we still have item/champion effect RNG like Curse Strike sometimes procs in the beginning of the fight, and sometimes it doesn't even proc. I understand that RNG should be part of the game, but seriously this is ridiculous.
