things being done a certain way does not imply that things cannot be done a better way
riot games has made it clear that their goal is to take the concept of dota and expand it beyond what they perceive to be un-fun or archaic game elements
expecting a player to multitask whereupon the one of the most important tasks is something bizarre, boring and extremely simple is dumb
imagine if you sat down to play street fighter, but your character gets more powerful as time goes on, and the only way to stay as powerful as the other player is to also play DDR at the same time
that's basically what last hitting is
ha ha ha! ha ha ha that's funny
you're doing the same thing with these complaints that people do with shaco complaints; assuming they're something that they aren't and then dismissing them unfairly
in shaco's case, people think they should change his kit - someone like you might assume it's because they think he's overpowered, but no, it's actually just because playing against shaco is really fucking unfun
in this case it's not really that last hitting is difficult, it's that last hitting for the first twenty goddamn minutes of the game is so excruciatingly boring that I have to wonder if anyone who argues in favor of it isn't literally a Hutt who thinks that playing a tune-less rhythm game for twenty minutes isn't the utmost kind of exhilarating
yeah man it's so dumb that people think that 'don't attack anything so that your minions get pushed back so that the enemy wave is under your tower so you can farm safely repeat for twenty fucking minutes unless lee sin decides to come stick his dick in your ear in which case you're fucked' is like somehow undesirable in some mysterious way! god forbid people want to actually fucking enjoy playing video games
