You have to actually click the game to see the build order. Its usually IE first if you look into it. In regards to SS being built 2/20 times, you may want to check back as the data on the site is primarily one person playing him. Most of the time you can see quite a few people using the Champion and get a better idea. For instance, if you look at the "different" people that played him, you will see SS/Ghost Blade taken as well.
If you look further into the build orders where BT was taken first you can usually see that they were forced to back multiple times early in the game. I'm assuming they take BT when they are losing lane and need the dueling power it offers through 20% life steal? Not sure, I'm not the best at this game myself.
I've also noticed a lot of time they can only afford
on first back which could be another reason I.E. is better. Building up to it gives you a lot more fire power if you can't afford the BF sword first back. Seems to happen a lot in pro games (happens to me too).
Like I said though, I'm not an "elitist", in fact I'm only in Silver. In order to learn though, I try to humble myself and realize that pretty much everyone Gold+ knows more than me. When someone tells me something, I listen and don't jump on the defensive with my l33t knowledge of this game, because I don't have it.
If I think something someone told me sounds fishy though, I do like to double check things. For instance, you think IE before BT sounds fishy. If you take the time to go through this website and look at everyone that plays Draven (not just Arrow, even though Arrow reinforces this in his build orders), you will see IE is the majority of the time taken over BT. Not only Draven, but most ADC's that don't rely on heavy AS to do their job take it first (ex: I think Vayne is different, I see a lot of BoTK first on her). There are however a few times where I actually did see BT taken first. As I stated before, maybe its the dueling power in a losing lane that is needed, I'm not positive.
At any rate, like I said I'm not in here trying to hound you about it. Just showing you facts through pro plays that Vayne Hentai is in fact correct in his statements towards you. Also that you should maybe try to be a bit more humble and listen to these players that are much better and more experienced than us. You may do great with Draven in unranked/Bronze, but I doubt that would carry over into a Gold/Plat/Diamond game (Where the people giving advice you shoot down play).
In reference to your question on making the screen wider, you just need a better monitor. I play on 1920x1080 and can see everything, but I also use my laptop sometimes (1377x768?) and can't see as much. Just a hardware draw back, if you see some type of program that says it will let you zoom out further, that is a hack. They had those in SC2 "Zoom Hacks" and people were quickly banned for them, so I'd recommend staying away from there :P
