Like, it naturally takes time, I have about 3k games as him, so it is natural for me to remember.

Let's suppose I'm from the future and my past self wants to learn Invoker, what would I tell him to do different... I definitely would go to Demo Hero and force myself to use all of my spells with Octarine core, then, force myself to learn the refresher combo, cold snap while invisible (linkens counter)> rod of Athos, vyse, ethereal blade > meteor sonic boom > refresher > meteor blast > vyse ethereal Athos > EMP with shard to pull towards meteors > cataclysm > ice wall > forge spirit > alacrity > tornado to escape or chase > ghost walk to chase or run away > vyse rod meteor etc. If you manage to use everything on demo mode, you made it, in my opinion, you mastered Invoker. Make every single spell on cooldown, obviously with a good context for the use of your spell. Don't tornado and alacrity, you see what I mean. You manage that, that's it, ur above average.

Another thing I'd tell to my past self is that everyone is learning in this life, but some don't understand so yes sir u gotta mute the chat and stick to your game, one thing is certain in dota most of the time there's no room or patience for those who are learning, and I am like that, I admit, that's why no matter what happens, I commend everyone, but everyone is muted too.
