I want to ask the community about what you all think are the 3 most broken match-ups in MP. I'm not talking about cheese builds here, so no triple steam tank or full gyrocopters or anything like that, but normal balanced armies that still find themselves in a very unfair situation generally.
My own top 3:
1) Wood Elves vs Dwarfs
=> All the magic damage from the Wood Elves makes their roster very narrow. Wood Elves have almost no non-cheesy answer to units like quarrellers and slayers (who even win against wild wood rangers!). The only way a Wood Elf player can win is by harassing a lot and waiting very long before starting a full engagement, which is then very frustrating for the dwarfs.
2) Chaos vs Vampires
=> Chaos has a lot of trouble with undead war machines, especially the mortis engine. Blood Knights can clear your mobile units and then the Mortis Engine can circle around the slow chaos units and drain them to death. And even the most elite chosen are not immune to fear caused by simple summoned zombies.
3) Greenskins vs Bretonnia
=> The Green Knight, even though he is green, is hated by any greenskin army. Only Azhag can really threaten him with spirit leech, but he is easily killed by your flying squad. Your green knight will be near immortal against the non-magic greenskin army and he can snipe out lords and heroes very well. Greenskins desperately need leaders to stay fighting and the terror that the Green Knight causes only makes it worse.
What are your top 3 broken match-ups and why?
