I have played this game actively since release. And I have yet to find anything weak or shallow about it, but that is my opinion and not yours and I respect your right to have an opinion. However if that is your opinion it is also my opinion you are in the wrong place.
However I must congratulate you on being the ONLY person I have ever found it necessary to ignore on this forum do to trolling. Just because you do not enjoy this game in the way that many RPG players do does not give you the right to troll these forums. Please be constructive to the over all discussion or leave these forums. I find it sickening to ever need to request this of a member of what I find to over all be one of the most enjoyable forum communities I have been apart of.
If you wish to express your negative views of Skyrim please do so in your own thread, and not troll a rather respectable member of our forum community simply because you do not share his opinion on the importance of the tactics involved for some peoples way of playing the game.
Yes Skyrim has flaws. No one here would deny that. But you have been a pest I have noticed in many threads of these forums and I do not appreciate your trolling of our forums. So please cease your trolling and nonconstructive behavior to our forums or quietly and politely leave. I find it rather upsetting to ask this of you, but I feel it may be what is required for the integrity of these forums.

Fight's over, don't restart it.
First of all, thank you for being the first, other than me to post a Battle Tactic. I'd call it more of a Strategy, since it seems geared more for avoiding combat through Stealth, and Range, but it's nice not being the only one in the conversation.
Now, let me see if I can pare it down a little, eh? What you will NEED is actually a much shorter list. Step 1, a good Bow. Won't really work without one, lest we forget. I respectfully suggest one with Cold for the tertiary Slow effect (after the Stamina drain.) Nightingale, Finerial's End, or some random bow of Freezing, if you want to DiY, this makes it harder for them to flee the Kill Zone.
Perks: Stealth(1) because at range, you're less likely to be detected in the first place. If you're up to 80, where you can afford 5 points in this, they aren't going to be detecting you anyway, so further perks here are wasted (Unless you're going to get close enough to backstab.) Backstab, like Stealth is a gateway perk to get Deadly Aim. Here's where the meat is, do as much damage as you can with each shot. Likewise, Overdraw(5) with Deadly Aim does 6x base damage with each shot. Hopefully you won't have to shoot them twice, but if so, they'll be Slowed.
Eagle Eye is nice to zoom in, but Steady Aim only if you aren't any good at leading targets. Power Shot may stagger, but it's mostly a gateway for Quick Shot. Faster draw time means more arrows in the air, and faster killing. Critical Shot may mean more 1HKs overall, and raises the odds that someone will be Critted, or Staggered each shot. I'd skip on Bullseye, because at a distance, in the dark, it can be hard to tell if someone just fell over dead, or just Paralyzed.
Silent Roll is very handy, but you can stand up, and run faster, without using Stamina, and relocate to a low profile spot. If they don't know you're there, you can just crouch long enough to get the Deadly Aim multiplier, then run to the next firing position. Not saying don't get it, but it's not absolutely mandatory unless you're going for Shadow Warrior. (If you do, you REALLY don't need more than 1 point in Stealth.) The upshot of all this troubleshooting is this can be done with a minimum of 40 Sneak, 3 perks in that tree, and still be just about as effective.
Conditions: This won't work for every fight. That's why we have different tactics for different scenarios. The ideal conditions that should make you think of this are 1) Night, or darkness. Helps you stay undetected longer, or break detection easier. 2) a valley, though a Fortyard is just as better if you can take the Walls. 3) High Ground. You want to have a high vantage point for maximum number of open targets, and make it as tough as possible for them to reach you.
Good points on Triage/Target priority. I'd also add, Archers, and Rangers. If you're safe from the meleers, but they've got enough bows, they can still out shoot you. Your primary advantage is Range, but only on those who don't have it. Shoot the Archers First, then the Mages from out of their range, then kill the hell out of the tanks that can't reach you, and are too slow to catch up. And the cardinal rule of Rangers (they even named a perk after it!) KEEP MOVING.
