"Weak demons"??

I've already said that this is a silly topic. And I'll say it again. First, no one will remake the game because of Ereb. Second, demons are far from the weakest and can challenge anyone, especially magical races. Of course, they aren't very good against strong units like Haven with Dwarves, their defense is too weak, but against others – no problem.

Hmm... I didn't say that the game needs to be remade, but the existing demons are inferior to many others:
1. The start is difficult (Deleb doesn't count). Deleb is that hero who doesn't require much effort to clear out neutrals.
2. The starting skills for heroes are nonsense... I've already mentioned which ones... and you need an archer on levels 1-3 (any) to clear out mobs more easily.
3. And finally, devils are expensive.
Question: Why were demons made this way? I hope they will be better in Heroes 6.
