Thanks for all the attention and help, but i've managed to make a small modification just for one single file (unlock_shared_los.json) so the cartography is already researched from the start of the match, the mod its attached down below, fell free to change and tweak it as you want or maybe even add it as a option in the match menu. Its all up to you guys.
Again, thanks for all the messages and ideas.
