Beg for the Hero Built and Item Built Guideline?

Many newbie like to ask what to buy in the game and what skills need to learn from beginning the game so them can own in late game, but most of the time i strongly disagree play DotA with SAME item and hero built in everygame. The rules below are some simple guidelines from me so you can refers to and have your very own item and hero built.

Hero Built:
1. Learn the skills which can disable or slow and support for killing and ganking are always recommended.
2. Stat built which means learn your stat in beginning of game are recomended when you think you should have more mana and hp for farming and others skills are important in later but not in early game. Such as Luna.
3. Choose the proper skill need to be level up that actually really need to be up in early game. Such as Lina skill 3 are useless in early game, so you should draw it out, and also for example Spirit breaker skills 3, you should only learn only 1 level for it in low level. And also some slow skill, there are same slow rates and duration, so learn 1 level are enough such as cm in early game.

Item Built:
1. Never buy orb effects item duplicately or on a hero which have orb effect for his main skills.
2. Depends on situation to choose which item you should buy. If you a tanker, buy tanker item such as assault, heart, shiva, hood or vanguard. Bloodstone and linken is also recomended when you need for heavy mana.
3. For some short hp hero, but with high DPS, choose to boost your stats and hp with some item such as BKB. In the same time, lothar is also can be considered good for them to increase their survival-bility. After the basic survive item, built up a extreme DPS with item such as Deso, burick, butterfly or mkb.
4. For fast attack rates hero, life steal, maljornir, and also difusal is always a good choice for them, life steal give a good combats for them which allows them to tank alot in the battle which maljornir and diffusal did give a bad time for enemy when you have a good attack rate which supreme fast. Basher is also a good choice for such hero.
5. For Int hero or some killer hero. Dagger or phase boot is the basic item for them to increase their survivability and also increase their killing powers. Since them have super high dps skills, but them have short hp, and most of the times mana comsumption is high, so bloodstones is a good choice for them too. Such as DP and TS.
6. For supporter, you should always spent your money on wards, but when you have extra money, phase boot, and bracer are always good. When you have super extra money, mekam and hex is good enough as a supporter.
7. There are also some special case which such as NA, he have high killing ability, dagon is extremely suitable for him.
8. For AOE caster which need to skill in a very close distance, such as ES, tide and also SF, dagger is super recommended.
