You could have put this all in one post, just as a note. There was no need to post it as three separate entries.
But, otherwise, this is not a good idea. First, the game already has skill gaps, but you seem to be implying it doesn't, and that everyone can just be high ranked without any skill or knowledge of the game. Which... makes no sense at all, honestly. Second, skilled gun-play is already needed in the game. So, again.... what are you talking about?
Over-complicating things with weird trick shots wouldn't add anything of value to the game. It isn't indicative of skill, its just noise for noise's sake. The kinds of players who could and would do these kinds of things would be minuscule in number, at best, and the type that have the time and interest to just repetitively muscle memory the timing. There are also other games for people who want to play that style of game. This is a moba. It's about team strategy, map awareness, positioning, etc.
Trick shots, though... not so much.
, such as last hit kill that is a headshot gives some status buffs, or perhaps last hit kill that is a feet shot 
with 0 skillgap.. you wouldnt understand that why in league theres no last hitting but in dota theres last hitting, real moba have a lot of small things to make more skill gaps... moba is about efficiency if you do all the small things... u hav all the skills.. you are the best, and my posts arent the same, youre like a karen in a street
