It boggles my mind how people still suggest removing sandbags from mainlines, despite the balance team constantly telling people it's not happening at this stage in the game's life cycle.
These exact same people keep asking for completely new units to be put into the game. They aren't the sharpest knives when it comes to talking things within the realm of possibilities, they aren't even aware of existence of this realm.
If sandbags are globally agreed problem by more then Justice League of 4digitrank, then start from increasing build time for long range units that benefit most from them, so if you want to build them during cap, you'd have to linger there after you finish before you move on to next one.
