High-level mid Tinker guide

Introduction

My name is phsc, I'm not really a pro player, but I'm a 5,5k player, I play mid/carry, and Tinker is one of my favorite and best heroes.
TINKER IS A REALLY HARD HERO TO PLAY WELL, DON'T FIRSTPICK HIM THINKING YOU'RE GOING TO SNOWBALL, MAYBE IT CAN WORK IF YOU'RE LOWER THAN 2K MMR BUT DON'T DO IT, PLEASE, PEOPLE ARE GOING TO COUNTER-PICK YOU
If you want to learn Tinker, it's not like playing any hero, it takes time, and I would say it's a good idea to get on a older account/create a smurf to start playing him, or just play pubs, no ranked until your 20-30th game, if you want to win.

Skills

I could do some beauty thing with skills and numbers, but I'm not going to because it's useless.

Laser: Tinker is a really strong laner thanks to this skill, this skills blinds, so the enemy midlaner can't farm, and you can also harass him while doing this, or secure the ranged creep, later on you can do massive amounts of damage with it and Aghanim's Scepter with the lvl 25 talent, also, it does pure damage.

Heat Seeking Missile: This skill is what is going to defend your high-ground, while also harassing the enemy midlaner and also securing kills, it goes to two enemy heroes but with Aghanim's Scepter it goes to four enemy heroes.

March of the Machines: Tinker's farming tool and defending high-ground tool, with this at level four, you can kill an entire creep wave with two marchs, remember this when you're split pushing with Boots of Travel, I'm going to talk more about this later, in a farming section

Rearm: This is what makes Tinker a good hero, you can refresh all your cooldowns of your skills and items, just a few don't, Black King Bar, Hand of Midas, Linken's Sphere, Refresher's Orb, Necronomicon, Helm of the Dominator, Arcane Boots and Pipe of Insight, with this skill you're going to do massive damage in teamfights, with giant pick-off potential, and also farming really fast.

Talents

LEVEL 10 : +6 armor is really good for Tinker as hes really squishy with a really bad agility gain, this will help a lot until you get your Shiva's Guard to survive a Stiffling dagger from a Phantom Assassin that crits.
LEVEL 15 : Tinker is really squishy, if you feel you're not going to die you can get the damage amplification, but I feel like the HP is better as Tinker has a really bad strenght gain.
LEVEL 20 : Casting March of the Machines from a safe distance is really important, so that's why you get +75 cast range, also works well with items and the rest of your skills to do damage, and will really help when you sell your Aether Lens
LEVEL 25 : +100 Laser damage is way better than the spell-lifesteal, because you're still squishy, you're going to die, simple as that, and the bonus damage makes a gigantic difference in team-fights

THIS GUIDE IS IN WORK, I'LL FINISH IT LATER AS I HAVE A LIFE, I'LL ADD ITEMS, MID LINEUPS, AND I'LL EXPLAIN HOW TO FARM WITH TINKER
