Weird. I'm diamond 4 on my smurf account which only had champs and runes from leveling to 30. It didn't hinder me at all. Some champs from the beta release are a bit outdated, but some of them are completely OP due to their simple design, and those who aren't get reworked and refreshed. Look at the meta right now, a lot of the champs being played are champions that were released back in Season 1. That means they've been out for around 4 years. Also none of the champions are nearly the same, Riot is very clear to make very unique champions if you have seen any of the last like 10 champions released.

Dota wasn't a game made randomly, it was a game made by a huge and very popular company. League came out in 2009 and was the first game Riot (a completely unknown company at the time) made, they had to decide their monetary system back then and stick with it, which they did. They didn't have some huge company behind them, if LoL failed Riot failed, where as if Dota failed Valve didnt.

When it comes to Dota giving someone all champions that isn't exactly a good thing, especially to someone new to the game. It can be overwhelming to have to pick from 110 different champions where as someone new to league has the 10 different weekly champions to pick from.

If you played any league you'd know that everything comes down to skill and knowledge, not champion matchups. Most of the highest rated players main one specific champ and more often than not these one trick ponies play "non-meta" champions. In professional play where the teams will only pick the strongest of the strong they still end up picking or banning over 70% of the roster.

You are simply misinformed and that's okay, just don't act like you know something about the game when you don't.

Also if you don't like the monetization of League you should avoid all of blizzards free to play games, as well as many other amazing free to play games. Which means you're missing out on many great games :⁾
