After a few games with this patch i feel they are going backwards with balance.
t5 feels bad, except the reaper + flash freeze (please make flash freeze and blizzard same damage type so they dont stack status res sunder -8 is too much)
the racial t4 like war breed and in particular templars rule
battle mages are uber strong now
How to fix? Limit the number of enchantments and remove the mythic tag.
I don't know what the magic number of enchantments per unit should be 3,4,5,... but they cannot be all.
Also don't try to fix multistacking with nerfing the coolest units the t5 with that mythic tag. t5 should always be the end goal. right now they are not.
right now it's all about racial t4's with race transformation+enchants. let racial t4 have racial + enchant to keep them competitive and buff the non racial t4 like the dreadnaught but bring back t5. they are not worth it atm.
Or start including mythic in some of the enchantments. The golden golem had 1 day of maybe he's good because of that damage buff that you fixed

))) again feels balance of units is going backwards. instead of increasing the pool of viable units you are bottlenecking it more.
Also i'm not sure but i think the giant clense is glitched or it is not it's super strong. Too many cleanses...
And another thing so many morale buffs these days morale damage builds are 100% dead.
p.s.
the fire templar also needs his fire resistance lowered maybe to 1 or 2.
edit: it's impossible to balance a unit that can get all minor transformation and all enchantments vs others that don't get squat. limiting the nr of enchantments would make it more managable to balance units and including the mythic in the enchanment buffs would allow them to be what they should be the apex predators of the battlefield.
edit2: before i forget crucible fortification is a straight downgrade. you lose accuracy for some bad damage and thouse things explode with your walls and burn your units...they are awful.
