My mistake. That is low, particularly once you do have him put on all the heavy gear.
So first encounter with Orc Warriors (4, plus 6 or so Young). They're veritable tanks: when they were first approaching, one of my guys managed to land a crossbow bolt on one's armour and it might as well had plinked off. Took off about 8% of its durability. I managed to land a lot of blows past their heavy shields, but they're huge (barely discernibly) green sponges. You can technically surround them and land near-certain hits, but a) I didn't have enough men, obviously, and b) they can STILL take a metric ton of punishment before going down.
I ended up losing four good men, levels between 4 and 6, not due to any BS roll but rather the sheer attrition of having to trade blows with these beasts for an extended period of time, until they finally give. One guy actually survived, but might as well have died considering the broken knee has crippled him for combat service. Another likely did die to a BS roll: clear shot from an archer buddy, guy in question was behind the orc and the arrow hit him instead. Handed the poor fellow to the greenskin on a silver platter.
I feel I have to reload and reconsider this contract. Losing four experienced fighters (not to mention their expensive armour) is just too much of a setback at this stage. I've only done so twice on this playthrough, after the Berserker massacre I described earlier, and the hopeless goblin situation I mentioned more recently.
Perhaps I had too many piercing weapons (4 spearmen, 2 archers, 1 crossbowman and 2 pikemen) and should've doubled down on bashing weapons like maces and flails instead, to deal with all that armour. I don't know. Could Orc Warriors even be reliably stunned, considering their big helmets? The pikes weren't all that ineffective, and the spears were good against the Young. The other guys were two javelin throwers with backup axe or sword, and I also had two reach-2 two-handed axemen.
Before I cry "NERF!", and boy do I feel the urge to, any tips on fighting these monsters? It feels increasingly like the mid-late game is going to be all about not getting hit, investing heavily on melee defense so mercs can weather the onslaught of superior enemies with impossible resilience. That, and of course supposedly getting "professionals". I'm still trying to figure out whether that's a real, viable strategy or something else that's fallen out of balance.
