Alright so let's talk about Vayne Any hp you build is negated by her Silver Bolts so what item do we use to counter her? Currently the only way through items is Frozen Heart and Randuin's Omen. Secondly, you can build whatever you feel is needed, generally, Vayne is very difficult to deal with in terms of out playing her as the only way to do so is to dodge her E. Generally, if you fail to do so and aren't very ahead, you'll probably die. Crit Yi deals with vayne the best in my eyes unless guinsoo's is already stacked.

Basically, you can go rageblade second but the way I see it is, why build defensivly if i'm going to die anyway? I may as well at least go 1 for 1 rather than 1 for 0.

If you build lord dominicks, and Blade Of The Ruined King, you'll find you'll kill both tanks and squishies very quickly unless it's a rammus or so. On hit is better to play in jungle because it's easier to snowball, and maintain that snowball, as well as easier to come back from when behind. Crit is better when played in lane.

I'll give it a whirl in some games I guess, but imo warrior isn't that good and the eye ball collection even if it's fully stacked only grants 18 AD which is pretty much nothing since it's more of a late game rune that doesn't offer much late game.

I'd say a better path is going your blue smite, and going up front critical strike with an infinity edge > pd > shiv, your aim is to snowball, not delay your spikes.

Celerity is pretty strong yeah, but wouldn't ghost be better than ignite? Ignite, sure gives you damage, but having a summoner spell to escape would be better imo. Also ghost gives like 5 AD or so thanks to Celerity.

I assume you mean by level 10 as in just recently starting the game/account.

My advice is do a standard clear, don't go for the raptor start clear I do on my streams as you lose a lot of hp, and tend not to get a good pull. Start buffs first, and go refillable potion, if you're struggling and are forced to back, start 3 potions instead.

Early game strat > farm till 6, if you see free kills take them with Ghost only gank if 100% certain you'd get a kill e.g. enemy Gangplank has no Flash and is near your tower, obviously he isn't escaping you. Once you hit 6, gank everytime your ultimate is up, but otherwise farm and see if there's free kills

Mid game, take objectives such as dragons, towers etc. Try to set up dives to get free objectives, but obviously ensure it's possible to kill them without dying yourself. Try to group with team if ahead, if not split.

Late game try and get a pick, and then group to make the fight 5v4. If they constantly group, split push but try to not give baron away. Make sure you ward, and know where enemies are before committing to a split, if they try to baron, try and at least get an inhibitor to trade.
