That's obvious, but you do realize debuffs persist through smokescreen and there is a delay between smokescreens so you WILL die. Also you're lack of knowledge is evident if you think life steal works in inferno, 20% of 3% dmg-to-life (TOPS) is nothing. It's like 720 on a crit(based on athenes average crit, don't forget he's wearing crit dmg gear too so it's not that much on noncrits).
It's also not something you will always be able to do. I could eventually make a video of me killing diablo without moving and just dodging everything, it would take time but if I can get my dmg high enough it's theoretically possible. On the flip side I could eventually make a video of me killing diablo without having to move at all and live through everything. While the latter is easily repeatable with gear the former is not and that is why videos are not good enough. Show me a video of you doing what he did, even with gear it will take more than one attempt.
You also said to just go for pure damage but now are saying you need life on hit to live. Which is a survival stat, basically you have no idea what you're talking about and can't be arsed to do the math for yourself or make an educated decision.
What I said will happen, it's inevitable. You can bookmark this page and come back 2 months after pvp and see who's right, just like all the people that said I didn't know what I was talking about with inferno and diablo's short campaign. It's really easy to piece together an accurate scenario when you base it tidbits of factual info, history and human nature. (Such as impatient, instant gratification seekers who always take the easiest route first and then correct their mistake. Afterwards they scoff at others for doing the same thing at a slower pace. On the bright side at least we're resourceful)
Sorry, but dying repeatedly is not fun for anyone. Though it is worth it to people looking to complete a game as fast as possible.(even I am in this group, I was in act 4 on the 19th or 20th) But once that's all said and done, you'll see what I'm talking about. It will probably be triggered by some internet star making a video showcasing how he can shit on people that have no dmg reduction or hp.
BTW You still haven't disputed anything I've said with logic and only echo what I said about it working but after many deaths. I never disputed that it will work, in fact I even said it will work, but it will just get you killed and is the wrong choice in long term.
