Just like those who played as Shakti, when they are given one stack of Troglodytes (and the second hero could be Lorelei also with one stack) and the Harpies won't be built either... In such a situation, IMHO 1 stack of Harpies with Lora is better than one stack of Troglodytes with Shakti...

Now compare the probabilities of the event I mentioned and the one you mentioned :D Or better yet, start 100 or even 1000 times in SoD and count how many Harpies there will be on day 111? And that's not even mentioning that their upgrade might be delayed until day 112... Add to that the secondary skills that Lora has and don't ask stupid questions anymore. And if you still have questions, answer this one: How do you take an external dwelling of dragons with Lorelei? Or does it all come down to a max Dwarf Cottage? :D (which, by the way, you'll hardly get with morale)

P.S.: In WT, of course, it's more pleasant to play as Lorelei. Many Harpies and scouting is very fitting. The ability to strike and not return back is very helpful, i.e., you can use Harpies like butterflies :) But in SoD, WHERE TO????
