Clan Angrund has 4 unique hero options which CA seems to be perfectly fine about without many changes.
In the same timespan the regular Master Engineer, Runesmith and Thane had a few changes.
Thane: -100g, +5MA, +5MD, +10 Base Damage, + 15 AP Damage and +5CB.
None of those changes had any impact on the price and stats of Halkenhaf Stonebeard and King Lunn Ironhammer.
Both of them are 500g more then the Thane.
Runesmith: +50g, -2MD.
Throni only got the -2MD, seems his price was considered to be high enough.
450g more then regular Runesmith.
Master Engineer: -150g some range attack adjustments with Gunnery wight release.
Dramar got adjusted the most with -100g and the same range attack adjustment.
450g more then regular ME.
There is no reason to consider one of them to be ok at this price, all were created with game 1 in mind yet the price did stay the same since their release.
While the trade for 75% phys res is nice and the added fear/terror very strong (though limited because its only a 32 speed platform) the loss of 1000+ hp,120 armour, 25% magic resist and 15% missile resist does not warrant their base price to be so much higher.
Just to compare at the release of TWW the Thane was 800g and the Runesmith 1150g now they are 500g and 600g.
Some suggestions and fun suggestions:
Halkenhaf and Ironhammer: -200g, which would leave them both at 800g also +10 Base Damage and +15 AP Damage.
Fun suggestion: Mostly item swaps to give them something unique over regular Thanes.
Maybe a ghost version of the Hammer of Angrund for King Lunn its his Hammer afterall.
Not sure about Halkenhaf, maybe frostbite attacks or the old itemisation the thane had.
Throni Ironbrow: -150g, would leave him at 850g.
Fun suggestion: Ancestor rune of wrath and ruin, just for him revert this rune back to either TWW1 version or the one from
TWW2 release whatever is easier to do.
Would really love Ancestor versions of his other runes as well but they didn't have that many changes.
Dramar Hammerfist: -150g, 900g after this change.
Fun suggestion: Its great that he has magic range attacks now, can't really think of something else.
Please feel free to add any other heroes CA seems to have forgotten about.
