How Does The Difficulty System Work?

[Syntax-Error]

I don't qute understand the mechanics of the difficulty system in warframe.

 

Each mission shows a difficulty level... like 1,2,3,4,5...

What does that mean? More enemys? Stronger enemys - Higher attack/defence values?

 

At the same time Each mission shows a level range... like 16-20 or 15-22.

Does this mean there are only lancers in low level Grineer missions?? Or do they become stronger in high level missions?

 

I play for quite a while now and so far i don't get the systematic. Also the entries in the wiki regarding this topic aren't really sanctifying.

The reason why i am asking is because i want to know how much shots i takes to kill an enemy with a certain weapon. So i have to know how the difficulty value and the level value influence the enemys stats.

To my knowledge, the only weapons capable of instagibbing high level non heavy enemies are the bows, the snipers, the Burston, the Latron, the Sicarus, and the Lex.

Hmmm... So every enemy has a set level... right? Is there a formula to determine how much damage it takes to kill a enemy at a certain level?

And what does the difficulty value stand for?
