Do you prefer armor or attack?

It's unlikely to be 10 10 1 1; it will probably be 17 3 1 1.

17 3 1 1 definitely won't work. Based on my experience (without artifacts and visiting arenas, mercenary camps, Marlet's towers, and the library, which gives +2 to everything), it will be approximately 13 4 2 3.

Personally, I would choose attack, and I only take defense for heroes with that specialization.
