"pretty sure" is not enough to make a proofed claim. we dont know because it hasnt been said so.
actually fel is directly opposite to arcane in the cosmology map. https://wowwiki.fandom.com/wiki/Cosmic_forcesFel magic is very similar to arcane magic
arcane is order. fel is chaos. they are fundamentally different.
because there is no proof of it and iam not going to assume to make an argument on assumptions. if its not explicitly stated then its not fact canon.and sometimes even better to do some things like portals, why it would not be the same thing just in different magic source??
you do not know that. there is no proof anywhere of specifically how the others got it. in the one from ashenvale, grom specially urges them to drinkand its canon fact, only few orcs drink it, Grom and varok were exemjples, Ogrin didn't, yet, every one of the orcs got corrupted and not just corrupted, but bounded to the Legion and Manoroth
https://www.youtube.com/watch?v=R77baYweLQk 25:24. there is no radiation thing. the words are very specific "come my warriors, drink from the waters and you will be reborn". That is all the proof thats needed. anything else is us assuming or inferring. Which would be irrelevant because we got a direct quote in a cinematic saying otherwise. The only argument would be, was it the same back in draenor? Or in WoD? did they drink again urged by Guldan in draenor and Kilrog/Guldan in WoD? As per Twilight of the Aspects, "Even those who did not partake found themselves with an unquenchable thirst for slaughter".
So:
1. we know they drank in ashenvale
2. we know warchiefs drank in draenor
3. we do not know how many drank in draenor if any besides the warchiefs
4. we do not know how many drank in WoD if any besides kilrog/guldan
anything beyond that is assumption.
law of sympathy was never used by tichondrius. you can imply that, but he never said that. the only place that is even mentioned is for arcane magic. and as already proven, arcane and fel are fundamentally different. There is no proof to refute the cosmology map.Tichondrius says the blood pact bind all orcs, not just the ones who drink it., law of sympathy
this is incorrect because Arthas was never really enslaved (one of the primary reasons why he might be in the Maw). And also incorrect because while the lich king was weakened he still summoned arthas to icecrown. Control or not, we know there was communication. the level of control we have no idea about.without ner'zhul and his influence arthas still did what he wanted anyway, and frostmourne were mere whispers, and when the LK lost control of the powerful undead, arthas would also be "free" like sylvanas, but he did it anyway.
