I wrote an overly long guide for beginners. My goal was to just focus on typical problems beginners have, but it got too long. I might slim it down later. Any tips or advice would be useful.
A few suggestions on the Last Hits section to make it a little more readable:
Last Hitting: The most important skill in the game. Last hitting is when you give the killing blow to an enemy creep, which gives you bonus experience and gold. No matter what character you play, you need to know how to do this. Last hitting takes a lot of practice and its easier to last hit with some compared to others.
Auto-attacking: This is a default setting that you can change under the "Game Options" menu. When disabled, your hero will repeatedly attack any enemy you right click on but
will not begin attacking the next closest enemy. This is useful in the early part of the game when you're developing a sense of timing for achieving the last hit on a creep.
There's a downside to turning off auto-attack -- when you want to kill multiple enemies later in the game, you'll need to right click each enemy in succession. This is less efficient than allowing auto-attack to move on to the next target. Experiment with the auto-attack setting on and off to understand your preference.
Similar to last hits, you can also practice "Denies" -- this is where you kill your own creep/tower to prevent the enemy from gaining gold/experience. You can only attack your own unit when it's under 10% health. Right-clicking it does not work -- you need to manually attack it using the A key, then left click.
If you want to practice last hitting and denies, make a bot game, where you are the only hero, go mid, and practice for about ten minutes. Keep trying to top your score. Obviously it takes skill and practice, but the big thing is that you need to always be aware that you should be trying to get last hits, not just helping to kill the creep.
