Idea Necro rework ideas, Reposted

As you all know, Recently, necro has become one of the worst classes to play as In Game.
Which I sad, As necro used to be one of my favorite classes to play as. I have a few suggestions to make necro at least playable again.

Changes to the Player
A few changes to the player I would suggest, is maybe a bit more usage in the Sword or pickaxe, as the necros attack is quite frail, and cannot stand up to much more than an archer at close range.
Necro would keep its armor status, but you should at least give the necro a bit more attack value, like maybe knock-back on the pickaxe, like the engineer has. Or you could make the sword a bit more usable, as currently it has no use whatsoever, as you can heal zombies using anything you hold. Maybe Giving the sword Knockback 1 and Sharpness 2 would give it a bit more usability.
Changes to the Mobs
As you know, the Necro's main ability is to summon mobs, and can be a bit difficult to do as you start with zombies. I suggest a few things to change the impossibly hard aspect of getting zombies to kill anything.

I suggest that if a zombie does in fact kill a player, that it should be given whatever that player was wearing and wielding. It seems overpowered, but have you ever actually seen a heavy go down to a zombie before? Players like heavies or soldiers are hard to kill as a player, and therefore will not likely die to some zombies.

I also would Like to add that zombies should be given a 15 second speed boost and a 10 second strength boost as they spawn, just to get them into the action faster, and to give them a fighting chance against players.
