I'm not quite sure what you're getting at here because your argument construction is piss-poor, but if what you're saying is Riot nerfs and buffs champions based on trying to sell them you're completely wrong. Riot has so much money they can literally shower money on whatever they want (E-Sports for example) and make it grow. Riot is indisputably one of the most generous company towards their fan base (Mostly because of how sodding rich they are). They don't need to make champions OP to try and sell more of them. I think you have a grudge, mate.
If they can shower so much money into E-Sports how come they had constant connection issues during the tournament, as well as teams cheating due to their own lack of preparation, and bad booth placement where people could turn around and see a minimap with the enemy team on it?
You are completely mis-informed. League of legends is ENTIRELY about counter-picking and team composition and out-playing your enemies strategy with your own.
How are you going to counter-pick a hero when you have to spend money or in-game currency to buy that hero? What happens if you don't have any counters to their team? Tough stuff looks like you get to lose because the game makes you buy heroes instead of letting people be free to try whoever they want whenever.
Complete bullstuff. You are completely wrong in this statement. Champion balancing is a major part of having a stable meta and Riot do it frequently.
Personal opinion - do not agree.
More bullstuff. Teams in league of legends do not run 'the same one-trick pony lineup' every time. Team comps vary from AoE to Assassin to Poke comps and Split-pushing comps. The meta won't change this in either game.
I'll give you credit for these ones, the last one was a poor choice of wording though. The problem is just because 1 1 1 2 is the ideal split doesn't mean you need to run that lineup every single time. Often sacrificing a perfect split of gold can lead to stronger lanes and determine the outcome of the early game, arguably one of the most important stages. Then again, hero bounties and cs gold ratios are different in Dota 2 and LoL so it's a tough subject to compare.
And yes, a lot of what you said is how League is much like Dota, and that's because they're based off the original WC3 mod, just not to the extent of HoN being a complete copy of it with a different coat of paint. Some of League's heroes share similar skillsets but that's bound to happen eventually.
