Seems like Modo is getting a Steam Exclusive edition that's aimed more at modding and enthusiasts. This might be a good alternative to MayaLT if it's a lot cheaper and allows commercial usage. http://store.steampowered.com/app/244290
The description says that it is specifically for people making DOTA2 items rather than the modding community at large, which is an odd choice on the Foundry's part. I'm not entirely sure why anyone would pay for software like MayaLT or the comparable Modo version when Blender is free and just as capable.
