Well, it's all about the combat basics at this point. Basic numerical values e.g. for cooldowns that in a single action don't have a lot of influence but as they're constantly used in every combat and every action therein their influence on what happens stacks up dramatically. From day 1 in the beta the "competitive community" how they like to call themselves euphemistically complained about the fact that your character cannot move a sword as fast as they IRL can do a mouse maneuver, which is of course a difference of day and night to have a tiny computer mouse movement which you instinctively learned is just enough to tell a computer program which action you want and with it execute a whole swing of a heavy sword or lance. Which in itself is not a problem, after all, it's a computer mouse. But it becomes a problem if you learn day in and day out to stack a high number of short movements after each other without the program to signal to you "Nope you can't do that, because your first swing/feint isn't even at 15% yet". So in this way, it's simulated the force you have to put behind a movement it to be effective at all and which a human can even muster. You need an extremely high ping to even be in a position to conceive of what the other is doing that way. Which is a problem with all fast-paced games of course but extremely exacerbated if every tiny mouse movement is translated into direct and lethal action. It increases the amount of stress of heightened awareness you need to play and at that constant rate it's just exhausting.
And that's just one enemy. Multiple enemies simultanously in BL is hard enough, but you can kind of develop a rythm for it, where with 2 of them you can block and swing and move so that you can still anticipate what the other MIGHT POSSIBLY do next. With 3 enemies you have to be a master in BL. Impossible in Warband, where you have a much higher frequency at which swings/actions are/can be executed. Of course to counter that they want to stack up in groups and train every one so that the disadvantage for them is at least completely compensated. And on top of it they are doing sessions where they sit day and night and observe exactly the weapon range and radius and speed and what not of every weapon and thereby multiply the problems you get when you face them. Of course you can also do that with BL now, but you need a lot of members in the group to be an AS impossible to beat force as in Warband. The problem is in the details and on a broad spectrum. And then they come here in the forum and proclaim completely dumbed down black-and-white "You just want the skill ceiling low", yea, low as in somehow managable with reasonable practice without getting a divorce and fired, not low as in teletubbies game or even standard casual what you can learn it once in 2 hours.
In conclusion you cannot prevent people practicing and getting better than you, but when you have multiple ways that multiply each other too much than it becomes either a stressful chore instead of work or you have every new and casual player resign instantly and probably not come back so fast. Not only that but it degenerates the amount of realism and thereby immersion a game can offer.
