So I circled back around to this game.
I've been sitting at the last siege of the Shadow War forever, just putzing around leveling up my guys. Hit the level cap a while ago and, still procrastinating horribly, have been going region to region leveling all my captains up to 80.
I've also started a complete purge of the ranks. Anyone with a meaningful weakness has to go, even guys that have been with me from literally the start of the game. The only weaknesses I tolerate are Beast Fodder, because even without Beast Slayer, most beasts get taken apart in one or two attacks by level 80 orcs. I can also live with Vulnerable to Stealth, since against players it is rarely useful more than once, and Online Conquests aren't exactly stealth and time-friendly events. If they've got both, they have to have at least two Epic traits. Anything else, they get vaped in the Garrison. It's actually not too onerous. By the time orcs are getting generated around level 70, I'd say 40% of them they get rolled with no weaknesses.
In replacing the marketplace, they made it so most Training buffs can now be bought with Mirrian. You can upgrade normal captains to Epic or Legendary, at a very hefty Mirrian cost. You can enchant their weapons, give them gangs or give them a few select Epic traits. The trade off, besides the rather exorbitant Mirrian cost, is that they can only ever have 1 Epic trait at a time (2 if you upgrade them to Legendary), so it's still possible to get better Captains generated by the game, who might roll with 2 to 3 Epic traits, than the ones you can build yourself. There's also plenty of traits you either can't buy your way to, or have severe RNG trying to roll up on your own. So it's gotten nice and flexible. If you find a normal Captain who just tickles your fancy, you can pay to make him a badass now. It's a pretty substantial Mirrian sink too, so it's nice that it continues to have value long after the end of the game.
I've also got a little side project. I'm recruiting every Assassin I can that has no Weaknesses. I'm going to upgrade them all to Legendary and outfit them with all the goodies, then populate a whole region just with them. It should be on the order of 26 Assassins or something like that. I'm hoping they roll really rare traits like Necromancer and Great Strength and Endless Rage too. I don't know if anyone even plays the Online Conquest mode anymore, but if someone does and manages to get to Level 80, I want them absolutely get wrekt when they try to take one of my fortresses.
