I only use Pickets when Lotus has not enough range to cover 3 mex spots against glaives or bandits.
You say> Build a line of them, and they become a safe space for your units to retreat and fight under.
Only until the enemy gets 2 Hammers and focus-fires Pickets. 3 Pickets and the 2 Hammers made cost.
You say> A suprise picket or 2 in radar-less territory can turn a glaive war and make your enemy timid.
Only if he is stupid enough to fight there instead of making warriors and repairing them.
Once you have enough to kill 1 warrior per fight, the enemy can morph a Shield into Shield Walker and it is much more effective than your defenders because he can choose where to fight with it.
You say> Picket is also extrordinary with it's flex AA capabilities. a lot of people build a razor, but I find it lackluster against anything but gunships, and even that it's lackluster against gunships like Nimbus, which can be outside vision range but within fire range, causing missed shots from radar dots.
You can build a 500m Radar a little bit behind your defense line.
It reduces Radar Wobble and your Razor will not miss any longer.
It also buffs Snipers and Hammers.
You say> If they build nimbus, no amount of ground AA will help me anyway unless it's a chainsaw or higher. May as well build swifts or mobile AA that can dodge. But picket helps every bit for air control. what are they concerned about 1 picket? what about 3 pickets? they may still engage my airforce over my pickets and I'm fine with that, cause that area is also ground-covered too.
You can use Razor also to tank shots against your statics. It increaess survivability of a Stinger if built in front of it.
Especially if you have 2 Stingers, 1 Razor and a Sneaky Pete behind it so that the enemy can'T queue attack orders with hold-fire units.
You say> I think picket still is very strong but situational. It works better when there are more pickets around. We have turrets whos job is to stop raiders for cost like llts and stardust, we don't need every tower to be unassultable.
But what is better? 4 Pickets or 1 Stinger/Gauss?
Stinger kills 1-2 Glaives per shot and has 2 shots before raiders do damage.
You can also repair it a lot better, saving metal in the progress and have less of a problem if the enemy chooses to flank your defense line.
