I'm part of the design team and as Sarahsh247 mentioned we are discussing the Floor Buffs removal.
The original intention of the buffs was to add location based strategy, similar to using terrain. A proper use of the floor buffs should be equivalent to having the higher ground, moving behind shelter or being pushed into a stream of lava.
We still believe having an additional strategy layer makes the battle more interesting and fun. However, we do agree the current floor buffs are imbalanced which is why we discuss what to do with them at the moment.
Given the team is focused on the new upcoming balancing change this was given lower priority until this week. We plan to make a decision early next week and we'll of course communicate it once it's made.
