actually, i think hots brutal is a lot easier
use keri to rape everything while u macro up an army
go mage build -> 300dmg single dmg spell, the dash aoe attack move, heal, creep bonus, mana regen, summon drop pod army
keep using 300 dmg spell on enemy defenses, make sure to keep ur creep spread up with ur keri's position, dash aoe on marines and other things u can kill in 2 dashes, summon army when u reach their base or for heavily fortified areas
all the while build swarm host and lurkers for d, then when ur rdy to make ur move teleport all ur swarm hosts to ur keri's position
