Why No Team Slayer Pro

Where has it gone and why? I have heard its gone so they can make improvements to it, i dont see why they cant just leave it in until improvements are made, being honest i get the impression 343 do not want a playlist like that or MLG, playlists that are based around skill and have no armor abilities/ordnance, better maps ect

It’ll be back in the new year as an improved iteration.
