I played 1250pts dwarves vs Gundabad but we followed the old lotr version of any kind of heroes and warriors without warband restriction...
He had like
Balin with durinss axe, Gimli, some captain then alot of dwarves (30 ish khazad) and the remain normal guyss with sshield, 2 handed and alot bows.
He totally had around 115 dwarves or so...
my army was made of azog, 2 gundabad caps, troll chief, mordor troll, 24 hunter orcs, 27 goblin town goblins and around 40 proxy gundabad orcs
He wanted to drag my army in at the dwarven lines meanwhile he would fall further keeping distance for shooting... he dragged balin and all the khazad and some shields to his left side to flank my force in a pincer move.. (it was a flank of 43 dwarves total, all D7 and 80% S4 nastiness...
Since I noticed his goading I waited a turn for him to push further back with the remain 60 ish dwarves while arraging my lines and then out of nowhere pushed suddent heroic marches and moved my entire army from my left side flank to engage his left side flanking force...
The goblins were the closest so I moved around to cut off his main khazad line from falling back and thrown goblins even on outnumbered matches to buy enough time for the remain of my army to get there.
Hunter orcs came crashing down on the enemy 2 turns after, 1st 1 or 2 going in then more and more flowing into combat along with some gundabads...
my main gundabad line started to move behind this dwarven flanking force to secure the cut off retreat line that the goblins initially had started. Once succeded I tried to bulk up the dwarves as close to eachother as I could (by this time almost all the goblins were dead) Then the big thing came up..... the troll chieftain and the mordor troll charged this bulk. The 1st crash they thrown dwarves deep inside their lines killing with some luck 2/3 a turn.. I even killed some of the goblins in the process...
Since the dwarves where so tight to eachother, any combat they would lost, would be like to find themselves trapped or pinned down by troll slams...
Azog dealt with balin easily and (imagening the scene, cutted the dwarf head off, dragged it up high with his claw hand and pointed his middle finger at Gimli who was a bit far behind with the remain dwarves and on sight to azog.
Game ended as my oponent realized the turned tables I did changing my entire army flank, as he completly underestimated me thinking I couldn´t think of strategy like him. He tried to push his entire army to help that flanking force, but the gundabad blocking the retreat line done its job holding them...
Trolls are amazing creatures, more if you tie up the dwarves with useless rabble.
Then throw in nasty gundabad orcs and hunter orcs and voilá... they get pretty much overwhelmed...
All this scene wass pretty much close to wat happened on min 2.03 of thiss video... literally like that , and I showed my oponent after the game lool
