Maybe an update is needed for the help videos?

Just tried the combo for today's daily-floating hoghouse. Used the combo in the vid but I was wiped out in the second wave! I thought I would have the combos memorized by now but I always refer to the help videos when I'm question. Is it me or do the daily dungeons seem even harder when you level up? I have level 41 toons with 6 and 7 mastery level. Thank you!
