Ways to make zombie mod better?

[JaX]

But because of these liberties for humans I had to give the zombies the Barrel Roll so that they can have an edge as well. Humans can use any gun and can spawn plenty of good props, so the Barrel Roll becomes a necessity for zombies to even the field. Zombies also have lower health than normal, making the Barrel Roll even more important.

Zombie Classes might be something I can look at though. But I don't know what the classes would be.

what i ment is to change the barrel roll for and infection bomb becasue the barrel roll is verrrry hard to use in situations

Zombie classes

-poisen zombie 10000 Hp 5% pushback 1000 gravity (uses the poisen zombie model)

-fast zombie 3000 Hp 100% pushback 300 gravity (can leap to enemys by crouch jumping)[uses the fast zombie model]

-climb zombie 5000 Hp 30% pushback 800 gravity (instead of breaking cades with E they can climb walls with E key)[could use the zombine model (from HL2)]

-normal zombie 7000 Hp 50% pushback 800 gravity (uses normal zombie model)

-headcrab zombie 2500 Hp 60% pushback 700 gravity (zombie with low Hp but when dead the player can be a headcrab that has 500 Hp when jump it leaps and if it gets on the enemys head its turns him into a zombie but if it hits somebody on the body it takes 4-5 hits to kill him) [the headcrab zombie thing can take a lot of scripting]
