I tot it wuz really cool at first when fire ayam show me this and wanted to learn but on second thought it wuz shiet due to the following reasons.

-Using the traditional drone patrolling at ramp before they block is much more better since it only COST 1 DRONE instead of... well the stack of drone recommended. If you are scared of getting kill sending 3 drones is still better than a stack of drones until lings come out.

-HIGH APM. I'd say at least 100 so not noob friendly.

- Not guaranteed successful. Even you break through 1 pylon there's no guaranteed there will be no cannon behind or re-pylon double to reinforce the wall.

-You lost eventhough this shiet successful as you used heaps of drones to do so which brings no income during the ordeal. Your heaps of drones cost more than their shooting wall L o L.
PS: Usually I think zergs use all out drones vs bunker rushes is because bunker rush got mobility and usually kill you if u don't stop it whilst protoss's wall just.. stays there which only keeping you out from ur nat and his base. Also, marines are much more 'killable' than pylons so it's worth.

-I Don't see ramp wall-off anymore. Is it me or the trend has switched? Nowadays the bunker and cannon rush is usually behind mineral line, between hatch and mineral or 'Special map spot' which could just fit some building in and auto wall off. The ones I usually get is ' 3 pylon cannon wall off behind natural mineral line.

-You stand better chance with 1 basing. You can either those tech all in or non- tech all in behind, even A wall bust to expend is better although you will still be slightly behind. It's your main task to kill their miners for scouting you out  during that.
PS: Protoss can -noclip their wall using the warp in trick. IMBA huh ?

For me this serves nothing more than for the luls
