I’ve always had an idea for StarCraft 2 which would really shake up how the game is played. Now I don’t think it would be doable at this point…but imagine this…
- Ranged units need a clear line of sight to fire at an enemy with very few exceptions (like the Siege Tank and Lurker)
This means that a ball or Stalkers couldn’t fire all at once without a very good spread. It means no more clumps of Marines stimming everything down. No more mass Roaches, etc UNLESS those units are firing at air units as a Marine or Stalker has lower elevation than air units, giving them clear line of sight.
Additionally this means pretty much all deathball play doesn’t work outside of VERY specific compositions. Colossus, Stalker, Zealot would still work due to elevation giving clear line of sight, Tank Marauder Marine + flavor tech units would also work to a certain extent as Marauders have elevation over Marines and Tanks fire over other units no matter what. Zerg would have Roach Hydra Lurker as their deathball strategy also as Hydras fire over Roaches and Lurkers; like siege tanks would ignore needing line of sight to attack.
Air units have collision. This prevents stacking large amounts of air units in one location, such as overlapped Vikings, Corrupters, Void Rays, Phoenix, etc. This mostly just changes how AoE interacts with air but also stops stacking air units to one shot higher tier units like Carriers, Broodlords, BCs, etc with other air units.
All AoE attacks have friendly fire enabled with more upgrades to reduce or completely eliminate friendly fire, where applicable. So for example, Lurkers and Banelings would be hurt very badly by this change, however, with the addition of upgrades which remove their friendly fire damage, this issue is mitigated (it could be a 30 second upgrade that costs 25 minerals at hatch tech, doesn’t matter. You just need FF enabled by default for parity across all races)
I believe these changes would radically change how StarCraft II is played as it would more or less put emphasis on small scale engagements across the map and pretty much kill Deathball play outside of very specific compositions. The game would take a lot more skill than it currently does to play optimally and we’d see pros start doing some truly cool stuff.
I also believe that it’s way too late for a change as radical as this and for something so massive, you’d essentially have to make these types of changes at the launch of an expansion.
Just a fun thought experiment!
