There are almost no truly balanced fights. Most all of them favor one guy or the other, by way of skill, gear, tactics or whatever. That's a fact of playing CF, and more times than not the guy who is favored to win does so.

Uncaballed warrior vs. uncaballed assassin as you pointed out. Warriors vary too much for that to be a good example. Random bash sword spec giant is bashing the assassin into oblivion without using any other command. For all the presumed tactics, it's going to come down to bash spam and passive damage output. If he misses, he just leaves the fight, or if the assassin lands the kote or something which shifts it against the warrior (if he doesn't get perma lagged). Luck very much leads to death in CF in probably hundreds of ways beyond DB firing, and if you don't see that, well, I don't know what to say. Evade firing to get me out of perma lag is luck. Basically any passive skill comes down to luck if it fires. There are so many examples of this in CF that you can't make that claim. Fact is, in CF you have to take into account the randomness (by way of knowing the RNG may or may not go with you) along with the things you can control. That's a lot of the fun of playing CF I find. Assuming this set of moves goes perfectly in a fight this outcome is expected, but if it doesn't what are my other options? How does that vary my tactics or plans? How will I respond? The randomness forces adaptation just as much as skill choice by your opponent, and so randomness showcases skill of a player because they are adaptive to fluid situations.

You want to see variety and utilization of all the things chars have in CF, but in most fights, its straightforward how the fight will go, and trying to incorporate other things leads to either dying, or the person getting away. I don't disagree, I mean, I hate the lag system because I believe command denial makes fights boring because you will see orcs doing nothing but bash and killing you with nothing more than savage feeding, and then there is pincer spam, staggered trips and all that other stuff. And yet, I'll still spam trip in certain fights, because that's how I kill the guy, not just make him run away. But it is a part of CF, and I realize more goes into it than just spamming trip/bash/pincer or whatever that allows me to win.

You want the game to be Street Fighter it seems like, where you each have a skill set and how you use them to attack and counter the other guy determines the outcome. In CF, fights are set up by the char's whole existence. That takes into account their gear, preps, skills, powers and skill %s and everything else that goes into playing, which allows them to have a set of things to attack and counter with.

That's what makes what you do with a char matter, you want to assess something like DB in a vacuum when it doesn't exist in one and can't be viewed in one, nor can any singular mechanic within CF.
