Experience from Monsters in Heists
While there's currently no experience penalty on Heist monsters, we agree that in actual gameplay, they don't grant enough experience. We plan to significantly increase the experience that Heist monsters grant, with a focus on monsters encountered during Lockdown.
Heist Areas (in maps) are too long
We're going to standardise the size of Heists so that once you hit maps, they don't get any larger than the current Tier 1 size. You'll find a greater density of reward rooms in the higher-tier ones, of course.
