While I agree in some respects (after all, my guide will never have videos to go with it), there are many people who also need to SEE that something works and not just have some "expert" tell them it does. The one thing I *do* like about videos, especially for strategies that DON'T work, is it makes it easier to know WHY the strat fails when I'm testing it. I've seen a number of videos where the fights go beautifully, but that is because the enemy pet never gets a 3-hit flurry, or the friendly pet always rolls a high hit, etc.
Some people can run a strat a dozen times and swear by it, yet it still doesn't work when I test it 5 out of 6 times. It's all about that evil RNG - and while almost no strat is safe from enemy crits (especially on big hit abilities), many don't compensate for the RNG intrinsic in things like high/low and multi-hit abilities in the commentary/description.
All I can say is if you are doing a guide/video don't just use your results to justify belief in a strat (other than ignoring crits on fights where the enemy doesn't have a crit buff). Look at your and the enemy abilities and see if there is something like a damage range or multi-hit ability involved. Channel a little Jerebear and do a little number crunching on it, and if you would have died if they did a high hit or gotten that 3rd quill in your face, or the enemy would have survived if you didn't always get the 3rd flurry hit each time, make a note of it.
Because when something is 50/50 that's not good odds when you have dozens of people trying out your strategy.
