The most difficult alternative

Come on, why are you so critical? Magic arrows against neutral creatures are much better than the rest; I always did that (until I started playing online:D). And in general, taking monks from Haven is great, just like taking mages or golems from Haven – there's no difference. After that come genies and titans; you can't say it's the best combination, but it's still effective. Yes, I take naga, but there are situations when it's better to take genies, and against neutral creatures, genies and titans get rid of them much more easily without losses than naga and titans (there are creatures of level 4 that can one-shot a naga with one hit, and that can happen very easily), and genies deal with them more easily and quickly from a distance.
And venomous snakes from Necropolis are no worse than vampires; they hit very hard, and cyclopses, in general, there are quite a few creatures that can shoot and defend themselves;
