RIOT, DO SOMETHING.
We took out haven and put it back in without any map changes, and we are still stuck with abysmal retake probabilities in all levels of play. (excluding Bronze and below, even then it is still offense sided)
Its not just Haven with these problems, there are many maps coming and going from the map pool with little to 0 changes, and it is not looking good for the future of riot's map balance. Over half of the maps in the game need balancing, Split, ASScent, Breeze, Shitbox, Haven, and Fracture. (Minimal changes for Fracture.) All of them have been or are out of the map pool, and none of them have gotten significant balances, if at all. Most of these changes are easy to see and somewhat tricky to fix, but it should be very doable in the amount of time these maps are out of the pool, and yet, it doesn't happen. This is very worrying for the future of maps that went out of the pool, more notably Asscent.
Who knows, maybe if we had a replay system they could have fixed this earlier.
TLDR: Riot needs to focus on map balance ASAP
