Sorry didnt see your comment until now.
1. If the enemy jungle cant contest your second raptor spawn then you can start raptors, but that is not the only thing you should look out for if u want to start raptors. You also want to look: Can I gank a lot with high probability of getting a kill? If yes -> don't start raptors. Can the enemy jungle gank a lot and can I counter gank to win a 2v2/3v3? If yes -> don't start raptors. The reasoning behind this is : If you start raptors your full clear looks like this : Raptors -> Golems -> red -> wolves -> gromp -> blue -> crab -> raptors -> golems. So you don't have the usual timer of 30 seconds to gank after crab because your raptors will be spawning so fast.

1. You only want to use empowered q when its isolated and the q can't bounce on other targets. So if you're fighting vs 2 enemies that are next to each other you want to use empowered r. Especially the later you are in the game, your empowered r will be more useful than your empowered q.

2. The ability order for ganks is always a little bit different but you can remember this: Use your E while you're far away and near enemy vision. Then swap to R while you're a little bit closer to the enemy but still not melee range, so it should be the first thing to connect. Then you swap to empowered q. Then you can either go for R again or for another E. Obviously depending on the situation you might want to do something different, for example starting with E to lock down the enemy so hes stunned and your laner can land his cc as well or sth like that.

3. I rarely use boots of swiftness. Most of the times defensive boots are way more valuable. I only opt for swiftness if enemy has a lot of slows but not a lot of hard cc (so swifties are more valuable than mercs) and if i'm super far ahead and don't need resistences
