By the way, another advantage of the conversion is a slightly different set of folders. At least three more heroes complement this not very diverse list. And Tamika, it's unclear how to defeat her if you give her time.
Or are you referring to Klancy? Well, he's not a very good hero. And Tamika is okay for other castles, but you still need Gosh to start with Necropolis.
Fafner, Rashka, Synka, and Yog are weak even with new skills, although I remember someone trying to make Yog work.
It's funny that Brogh becomes weaker with new skills, because spamming ducks is a boring task; Thazar looks more promising.
And Moner, of course, is a mega-hero. Flax generally improves with new skills.
