Well I mean if you want to get technical, it IS a bit unfair for Uberent to give some people Commanders that others don't have access to for money. I just don't have a problem with that because I don't think PA is meant to be a competitive or serious game - for god's sake, you're smashing planets into planets man! I don't think the developers are under any illusion that it's meant to be seriously competitive either, so whatever small imbalanced is created by giving some people access to specific Commanders is quite irrelevant in my opinion.
However, Riot claims that League of Legends is an ultra-competitive game where everybody is on an equal playing field. Well that's not true is it? If one person has access to champions, runes, masteries, or rune pages that another doesn't, then it's not an even playing field. You can SAY that they are all perfectly balanced with one another, but we know that's not true, so who are they fooling?
In other words, I feel like you're comparing apples and oranges. If League of Legends was just portrayed by its developers as a casual, goofy game that people play for fun, then I wouldn't mind their system. Unfortunately they want to make it out to be the best e-sport there is (and shut out all the competition in the process through exclusivity contracts), and I'm sorry to say but there's an extremely contradictory message being given here.
