My plan this week was just to do some quick low level mythic plus. The first affix this week was Teeming. There are easier affixes, and there are harder ones.
I managed to complete a level 5 within a 2 chest timer, and saw that the second affix was Skittish. For a team of 5 tanks, skittish hardly does anything at all.

So I decided to really push my team to the limit on mythic plus levels this week. I've never done that before, and I probably will not do it again in the near future.

I'm using strength flasks and potions of prolonged war. I also used invisibility potion once. I'm not using the potions of old the old war. They do a lot of damage, but cost much compared to the other potions which are cheap.

I didn't complete this on my first attempt. Without using old war pots, the timer does not leave much room for mistakes.
Anyway after learning how to handle the trash (and bosses) in an effective way, I made it.
