If jammers don’t get a size increase; this would be a helpful change for larger maps.
However, I think jammer should get radius increase (to point scout movement indicator can just reach the middle, so 110m); then players can just keep to opposite side of jammer from drones, and easily avoid detection. This solution will let the scout still punish those that are aggressive and push past the jammer on drone side; but give a way for those who want concealment to keep out of range.
If it were larger, and prevented marks in it, it would be OP I think, providing huge area with no marking ability.
Just my two cents.
