Legion Timewalking Mage Tower 10.2 - Holy Priest

To go from 1 shotting Restoration Shaman mage tower, to wiping about 50 times on this in P1.

P1 is 10x harder than any other phase, but other phases have easy and stupid wipe potential, making the process of re-progressing through P1 very annoying.

Too hard, this for me was probably one of the only real 10/10 difficulty mage tower challenges (along with Prot Warrior), which massively took away a lot of the enjoyment from it, but very good to learn from. P1 was just totally brutal - it forces you to learn the encounter to perfection almost, and even then it's still just so hard and a lot of luck dependant. Other phases much easier, as mentioned, but still can have stupid wipes and then might end up getting stuck in P1 for another 10-20 attempts.
