i think spawn protection is good way to defend your egg just saying its useful in sometimes
In addition to what Earth said ^, spawn protection isn't supposed to be used as a way to defend your egg anyway. It was only added in the first place to prevent enemies from spawn killing you over and over again to farm points.
I like the spawn protection, if it wasn't there would be no way to protect your egg if you just died. And it only lasts about 5 seconds, so i dont think its worth removing it.
If you couldn't deal any damage or anything while the spawn protection was active I wouldn't have a problem with it, but the fact is people abuse it and spam hit you off the edge into the void or just be generally annoying while you try to break the egg.
Think of situation like this: You have killed the full Green team on your own but your own egg is gone while theirs still remains. You go to cross the bridge but Green has already respawned. Now you have 5 naked people running at you (who you just beat in PVP fair & square) on the bridge that you can't hit away. You almost cross the bridge and then one last guy spams his fist at you and sends you plummeting into the void.
How is that fair...?
So yeh I agree with this suggestion +1
P.S I know in that situation there a ways to avoid them hitting you off, but the point still remains.
