This post is simply you quantifying your own personal skill, but that is not the point of the topic. Perhaps you're a good player. Perhaps not. Either way, it is irrelevant to the assertion I've made that players who do not want to speedrun tend to not be very good.
So, to reiterate what I said in the post you quoted, somebody isn't a bad player because they don't want to speedrun. But in my experiences, people who don't want to speedrun have been subpar players in a fundamental sense. (Using Doton on a single target, failing to hold aggro off of lower-geared DPS, being unable to heal people during light damage in a single pull, etc).
That is not to say I think that everybody who chooses not to speedrun is a bad player. It is just my observation that many of them have been subpar players.
Let's pose the question of the relation between preferred playstyle and personal skill a different way: Which would you say takes a more skilled group of players to pull off?
-Pulling one pack of enemies and dealing with the damage output from that pack as a tank or healer; or
-Pulling multiple packs of enemies and dealing with the damage ouput from that pack as a tank or healer?
With your answer, I'd appreciate if you could quantify why you think that your answer is correct.
I appreciate your continued responses. I know this is a topic you don't like discussing, so it's very good of you to stick around.
