GGG - are we going to get cumbrous crossbow

Found this crossbow on https://pathofexile2.wiki.fextralife.com/Cumbrous+Crossbow

When are you going to put it into the game??

Dont understand why is not in the game atm.

Its still early access. They have the frameworks up for several new items/skills/mechanics that are not fully implemented because they still havent finished. Like you can find data for soul rend or reap or unique daggers. Its a process. Just wait until they are done i guess.
