[HoMM V]9 Race - Swamp! Is it needed?

These are just options. And what exactly don't you like about the flying unit? I mean, without the lizard rider, like in Might and Magic III. One tile, flies fast.
P.S. No matter how enthusiastic you are, you can't create a new race on your own. You need to think about a team, and a big one. This is just advice. ;)

And I'm not even trying to make the game myself. First of all, I'm not a very good designer. And I'll have to ask someone else to do almost all the graphics. I can only be a programmer; I can handle that part of the work. I will need a team, and you're right about that. ;) But that's all for later; Tribes of the East hasn't even been released yet, and no one has tried out the Orcs yet, so there's no need to rush. For now, I'm just developing everything and looking for images that will suit the race, and then we can get to work. If we manage to create the Swamp Fortress race, then we can create new races afterwards, for example, elementals or something else; the main thing is to gain experience. :)
And now about the 4th unit. You see, not everyone likes the small snake, like in Might and Magic III, only at level 4. I also think it should stay; let's see what others say. I'm not Nival; I listen to what others say so that it turns out as well as possible, and not as always!:)
