In your opinion, which faction is the strongest in Heroes 5? Let's discuss the advantages and disadvantages of each faction.

Well, you can easily deal 1500+ damage with Ice Bolt at level 20, or barely manage 2000 with Earth Shock at level 40 – it all depends on how you play and how you develop your character... We weren't all born knowing how to play... Let the person learn, ask questions, and show interest. Why scold them for that?

The issue isn't how someone plays. It's the unsubstantiated nature of their claims, especially with examples that don't really match reality. Based on those, I can tell that they DON'T play against real people (at least not against decent opponents on ubi.com, and the level they mentioned is more suitable for a campaign than a proper duel). And claiming the strength of factions based on campaigns is just silly. If they want to learn, they should ask for advice in the relevant strategy threads, instead of acting like they know everything.
Maybe I was a bit harsh, there are many similar comments in this thread, and I shouldn't have singled them out (especially since they also made the claim that Armageddon doesn't work as intended, which is even worse). But still, if you look at those two posts specifically, I don't think I was being rude.

P.S. Demoralizing people is your right, but I don't see any valid reasons for it in your post.
