Earthrobot - pls buff it somehow

[Althend]

Lets take sky tank and compare it to the earth robot shall we.

Ok first off both tanks have a channeling spell that attacks ground, and both have a speed of 300.
Both tanks have a auto-cannon, and both have 8 armor
Sky tank is 8000 gold with 6500 hp

Earth robot is 7500 gold with 7500 hp

And a lot of people talk about how sky can outrun the earth robot, well earth robot with a speed boost has a max of 450, now the sky tank has a max (with its skill set to max and speed pack) will have a speed of 512.

Also remember with the earth robots transparent armor set to max will have armor of 17,
that is 9 more armor then the sky tank, also nether earth robot or the sky tank have a stun spell.

And one more last thing, you can buy a net to hold sky tanks for 3 sec, just tp in net and use earthquake.

The armor is not at all important...
And waste 200 each time you miss. The ground ability of sky makes 1000 damage each sec during 5 sec. (and it is not and ultima and does not need to stay still) The second ground skill do a lot too.
The sky is air, fast and is able to hunt and escape easily. What about earth? It is slow, it can't do anything against air (using a net ok...waste a slot and 200 gold each time you miss; even the goblin does have skills who affects really air)
