Best hero.

Yeah, Michael Jackson is the only hero with advanced shooting skills at the start. But there's not much point in taking him instead of Ivor if you're aiming for an elf-based strategy. Ivor simply has more of them, and after a couple of levels, he'll surpass Enova. However, she's good as a support hero, just like any other hero with a similar specialization. But Mephala is still better. Both in terms of appearance and abilities.

But Ivor himself will shoot like a hundred elves.

I thought his specialization was "Minefield."
