yes the reveal times ligner too long and too wide an area.
something need to change. so reactions are fairly treated
just like the zis barrage, follow up shots are too fast, and mostly your weapon crew are dead even if you hit fast retreat
The only thing that needs to change is OKW flares.
Any other flare requiers a unit to be fielded, moved where it needs to be and ability to be used, just like any other scouting ability in game that is located on a unit.
Its up only a fraction of time OKW flares are as well, so that "too long" arguments gets thrown out of the window.
UHU reveals much larger area and you don't even pay for it, so maybe nerf this instead?
Oh and if "follow up shots" are too fast for you, perhaps you should improve your micro and not let your weapon teams sit in barrage for half a minute instead of blaming irrelevant factor?
