If your ninjas are getting killed by magikills, then you're seriously using them wrong, and having spears against magikills are worse, because they're anti-mass for their explosion, poison spray, and electric wall. If you're fighting a mass of magikills with meric support by massing spears, you're gonna have a really bad time.
This is literally the most colorful post I've ever seen on SP.
You can, t make 80 sword cuz the enemy won't give you time to make them.
Dont forget that some players (like me) are rushers so they will attack you from begging until the end.
That's why sword mass is only semi-viable if the sword masser is slightly more skilled than other player.
