well a divinity is something that exeeds the power of anything comprehensible, and we are fighting them ATM, soooo ehhhh…
you literally just skipped the " time travel " part where i literally mentioned that we’d know an INFINITE amount of time befiorehand, and its very easy to just create the shield far above the planet so nothing hits.
also…there is another way of destorying the ship and we dont even have to use the forge ( even tho directing its power to the ship is WAY easier than making the planet shield )
- teleport as much cannon fodder as possible to the ship
- get a powerful mage, the scepter of sargeras, the book of medivh, and the eye of dalaran. ( jaina can do )
- re-cast the spell that exploded a planet and flung half of it to another dimension, the spell of conjuration. while it does need a celestial event to happen, it says the event only gave him some power. we can still cast a portion of it and your ship is DEAD.
other things to add :
-
the lich king has VERY close to direct control of souls, almost as much as malthael himself. and during the battle with him he was playing with us until he just killed us all with a snap. he was not weakened much at all during the assault. so it is VERY plausible to say he can literally go to your ship’o’sadness and yeet anyone coming too close to their death.

about the " rag can burn from plasma " thing…well it works, if youre anything BUT an elemental lord. if you get a creature thats 100x the fire of ragnaros, they’d probs still die. but being an elemental lor yourself, means that this actually benefits him, cause he is DIRECTLY LINKED to fire itself. it can be proven because when we fight ragnaros on azeroth, he is much weaker than when he is closest to his seat of power AKA the firey-est place on azeroth or the elemental planes. meaning, that you can place him in front of the blast, and he can take it, because it becomes his new seat of power, if u get what i mean … nice try again… and yes i know how the world works :3 im young but i aint stupid, now you read about the very well known difference between an elemental LORD, and a standard elemental… its greath 
also guys, im actually very convinced that the starcraft universe is WAY more powerful than i assumed, and to be honest even though i played the campaign, im very astounded. but that is NO reason to also trash azeroth either…as i said, a single titan can grab all three races and eat them as lunch XD… seriously though, don’t think that because we use swords and armor, that we are absolutely stomped on. if anything, its actually plausible that we can win against every race alone.
1: terran.
here is how i theorize it will go:
terrans would be able to kill the low lvl nubs because their armor is cloth XD and would cause severe disturbance accross several areas … but there are weaknesses in their ranks. the elemental lords, i will say, will play the MVP against the terrans. firebats will essentially be exploded by will from the fire elementals, so they are discarded. tanks would be lethal yes, but powerful shamans can summon rock spikes or trap them even. and the biggest factor of them all: the wind and storm element… because of the fact that we have essentially millions of shaman players, and the fact that we have the windlords and titan keepers, who can also use wind powers, they would very likely destroy most aircrafts and would even strike lightning on the odins and the un-destoryed siege tanks. the only sky force that would resist these the most will be the sky cities that fire yamato cannons that i forgot the name of XD . but i’d say a very focused attack on them can be very efficient too. i do not think lightning has no effect on machines, mainly cause why the hell would they design something that blocks lightning. the troops most effective would be the pew pew fodder ( also forgot their name omg XD ) , and maurderers. but thats very minuscile compared to the bajillion other things we have.
- protoss:
a bigger challenge indeed!
the protoss will strike fast and acurrate, killing most unsuspecting players. and would easily corner the forces of azeroth. HOWEVER! there is actually a very easy and logical solution… the protoss numbered a muntiple thousand agt the end of LOTV, and since there were only like 5 years max that passed, you can very assurredly say that the number didnt change much. sure they fought amon then and they had numbers, but if you look closer, you can literally count a max of 500 in the whole " into the void " thing… so yes, its very plausible.
we would have the advantage of at LEAST 1000-1 here… A THOUSAND to one. meaning that, a single zelot, while so SO very storng, cannot kill a thousand. the golden armada will be troubleing however, while it is huge and powerful, we have a secret weapon other than the dragons , or the dranei spaceships, the hives of the old gods! the old gods are practically minature zerg swarms, and would be able to destory even a carrier if they swarm it enough. not to mention that if we group a thousand wizards together, we can probs make out of each a giant ball of magic which will target your ships. and deathwing and dragons to strike the smaller ships, when the old god minions swarm the long range, hard hitters. and we can use the previous strategies to destroy the spear of adun.
i wanna write a zerg one but my hands hurt from writing LOL i wanna play the actual game anyone wanna join?
