Aatrox: Rushing BotRK vs. Hydra, Starting Abilities and Other Top Laners

Hello, I have a few questions relating to Aatrox.

1) BOTRK VS HYDRA

I usually start out getting a as most people do as it gives you pretty good damage and lifesteal, two very important stats to have on . The active also helps you when chasing someone as it slows them, and the attack speed helps too. After this, I buy or , get and , get , and then the next items vary based on the situation.

However, I have seen builds where an player rushes a and then a , and then get , or , , and so on. This early build gives players a whole ton of wave push early game and also still gives them the lifesteal that they need.

Starting off with gives me early game damage and allows me to buy tanky items right after it, but getting a and then a gives you massive lifesteal and wavepush potential but makes you very squishy until you buy tank items. Which one should I do, or rather, which ones should I do in which situation?

2) Starting Abilities

Most Aatrox players start off with either their E or their W, but some start with their Q. I usually start off with E>W>Q and depending on the matchup and situation I go for a level 2 or 3 all-in (yes, level 2 all-ins work because summoners at level 16 seem to be stupid, and I also have ignite) and go for First Blood. However, I have heard of orders where someone goes E>Q>W so they have the knockup that can help them get FB, but they don't have any sustain. I have also seen people level up W>E>Q , W>Q>E, Q>W>E or even Q>E>W, and depending on the situation they all seem to work out in one way or another. Now, my question is, is my E>W>Q good, or should I consider some of these other skill orders depending on the situation (and if so, what situation)?

3) Other Top Laners

Now, can be a good lane bully, jungler, and split pusher in many games. However, there are many other champions that can do much better than him, such as Jax or Riven. I would like to learn to play another, relatively easy to play AD top laner, but I am not sure which one. I would like to see what you guys suggest and who you guys think I could learn.

NOTE: As a level 16 summoner, you may stereotype me as a noob as many other level 16s can be very, VERY stupid (trust me, those guys always end up on my team). However, I seen a ton of ranked guides and videos on the champions I play as (usually Aatrox or Karthus) so anything you have to say, however critical or complicated it may sound, I will appreciate it (as long as criticism is constructive and thorough) and try to understand it to the best of my ability. Hope that you guys can help me on these!
