I would honestly rather they just completely revert GoT, and if they still feel the need to change it they should start from there. Have the Shamblers only spawn on one side of the map at a time (top or bot) so teams are incentivized to actually engage each other and fight over the seed drops. Increase the cooldown of the Terror’s Sprint ability. Make it so Terrors can’t time out while waiting to spawn, but spawn far enough forward that enemies can potentially chip it down if you don’t get in it fast enough (like the Protectors on Volskaya).
I would keep the changes to the map’s terrain, though. It’s still fairly cramped, but it is better than it used to be.
