Which hero is better after level 15 if you focus on developing their core skills?

AndersonAD, why are you so own clinging to Combat? And the others too... You guys, have you even tried leveling up Magic?

Well ..why though ..I like magic a bit more ...in all games I play only as mages ...I enjoy watching movies if there is magic in them ........and in this thread I wrote about combat because I am comparing my experience in such a situation ..of course I might be wrong.... of course the choice of who to play depends only on the mood of the player himself..:)..
So I've weighed it ... combat..hard map almost no artifacts ..mage or wizard or etc..doesn't matter basically someone else ...because he can't really do anything.... but a fighter already has good defense ..combat is good ...well maybe he'll take a couple more crystals ...for a mage they won't play much of a role anyway:))))...that's how it is!
