Half of what? You mean modding the game? Cause if you do, you would be correct. I have not been a part of the Avalon team ever, so I have not modified the mod. I just wanted to share some ideas, and it has evolved into this. Currently I am working on the new enemies in areas of the biomes your class visited at the end of pre-hardmode. And I already have most of Oblivion's ideas floating through my head, so all I have to do is type them out onto a doc, put Xenforo code in, and I'll post. For now though, I'm not even halfway done. I would rather release a finished, tidy product than a product which has grammar errors, flawed, and hard to read. So that's why it is taking so much time.
Forgot to mention balancing. To balance an enemy, weapon, or even boss for that matter, requires me to compare stats from the game, to my suggestions and estimate accordingly, based on DPS, if it is balanced or not. Enemies and bosses are a pain, because of expert stats, but what is worse is weapons. Trying to make weapons balanced with enemies is difficult, especially when I don't have the ability to actually test them out in game. So I just have to compare stats and hope for the best.
And I am learning new things as I go along. Such as what AI types are, damage resistance, and defense, and how they contribute overall compared to weaponry. Now I understand why game balancing is so hard.
