Dwarves overpowered take 2...

I recently posted about a mini-duel facing Dwarves VS Forest gobbos (from Nemesis crown).
This campaign was disaster for me as my gobbos were totally unable to best of the dwarves.

Now, we're replaying some kind of duel (but with 3 warbands each that faces each others in succession).
I chose the Necrarch from the Sylvania setting and 2 other warbands ( Marienburgers and Battle monks).

I manage to just KICK the ass of the dwarves with this warband. The vampire is a real nightmare for them. Ok, I got lucky, I git two skills as my first advances (Mind focus/sorcery) and lifestealer as spell so I manage to go through the difficulty roll about 70% time and I have the staff of damnation+the book of the cursed. TADA ! Go f**k yourself with your high toughness, resilient, master of blade, grombiled armor little greedy bastards.

Now my friend argue my vampire is unbalanced and bla bla bla....

I just told him to stop trying to put him out, try to avoid him as possible and go for the other heroes but he is too stubborn. He wants my vampire DEAD... but killing something that moves on 12'', has 4T, 2W and that ''sucks'' wound and cannot be stunned is pretty hard... As I told him, the vampire is my ''masterpiece''. All other warriors cannot face him (except the thrall maybe).

Do you think this warband is unbalanced ? Do I just got lucky?

By the way, His dwarf warband is really still a danger for my others warbands. He is playing Ogres and Lizardmen too.

4 heroes, 2 with grombil armour+shield+helmet,, dwarven axe+crossbows and 2 troll slayers with 2x dwarven axe, master of blade...

Against my Marienburger this is a nightmare for me (not enough strenght skill access), I was planning to buy rapiers someday but I finally left aside this idea. The battlemonks have some chances (thx to raging peasants that can ''hold'' one of his armoured tank).

The dwarves are a pretty good warband... but they have flaws... I see them now...

I played Dwarves a lot and yes, they are very powerfull if they don't loose badly the first rounds .. but they lack mobility and need a good sense of position (and abstract thinking) to take full advantage of this warband strengths.

If he is static, rolling dice from his position hoping to knock down your vampire .. is not going anywhere

If he has not taken the right academic skills (the 2 for better positioning the warband before the battle) the right scenarios and some high scenic element could be his nemesis.

p.s. have FUN!!!
