It is worth recalling that the first, far from ideal WG approach on this type of game already took place in 2015, when they presented the Deathmatch mode. The idea, however, was quickly abandoned.
Yesterday, when Battle Royale appeared in the Sandbox, many people began to share a movie that shows a short preview of such a mode. Of course, in 2015, Wargaming.net rejected the idea with the help of the players’ feedback. The main problem was the difficulty of playing in such a mode, the smoke, which caused significant FPS drops and the lack of appropriate maps. On the other hand, it may be good that this mode was not launched at the time, because it would be much less varied (no equipment, no loot from opponents, etc.) than it is now.
