Regarding the explorer, sorry if I ask again, but you made me curious. How would you build an assassin (Not an ambusher which seems quite impossible to me) in order to reliably kill an explorer?
Consider the explorer of strength 8, and +100% defense bonus.
The assassin has strength 8.
what promotions would you give it? Let's say a level 6 assassin. Aiming to have more than 50% chances of killing the explorer. Because I just can't see how it's done. Unless you try to a first strike heavy build? I don't know, enlighten me
Apart from that, a better solution for the explorer rather than strength 8 would be either to make it stealthy like ambushers (normal units can't see it, just beware of dogs and similar), or to lower its strength but increase its movement (move, look, fall back)
And no, I don't use explorers either, because they'd be unbalanced silly if I did (woodsman 3 + guerrilla 3 + a hill/forest tile is defense... +175%? The perfect bait-kill machine)
