Never paid a ton of attention to the mechanics of troop replenishment, but I've found certain notables reliably have better troops, as in I can do a recruitment loop and hit them twice and they'll have good troops both times. I assume it's connected to their power etc. But it's all very random and out of my control, and I agree that as a higher level clan there isn't a reason we shouldn't be able to set up a barracks that spits out at least tier 2 soldiers. I'm sorry but I would never in real life lead a group armed with kitchen knives and pitchforks into battle, that's not where basic training is supposed to happen. Even if we have to grab the recruits and drop them of for training.My issue is that I feel like the game doesn't give you a solid way of replenishing your forces other than mostly tier 1 units, even in late game.
But that clearly isn't the experience for some other players like @Apocal for some reason. He claims his cities are always abundant with t2-t3 units.
