I have to disagree on some major points here.
One I think doom of malan’tai was looking to be a major contender for tournaments and was taken out.

Now here is the thing.
First off we have an extereme meta game pointed toward mech list anyone who tells me it isn’t is a dirty filthy liar.
With lists like the leaf blower running around vehicles are the bees knees.

If Doom was ruled to be able to effect troops in vehicles it would have been a major shake up to tournament lists because you can no longer crowd the deployment zone and sit and gunline your way to success.
However that being said I think that that ruling is fair because it says in mounds and mounds of fluff that there is spirits in the vehicles or they troops have absolute faith wile inside a vehicles.
That and it would cause multiable problems with other rulings.

However the ruling that people get cover saves.
Ok so doom is sucking your soul and whats keeping it in is the fact your hugging the trenches.
Exuse me?
Any wear it uses it’s gaze to touch it’s minds eye is so stuffed that not even the armour of the mighty terminators can stand against it’s cataclysmic vortex of souls those entering and those leaving.
But, your building protects you.
This took doom from being boarderline to unplayable.

The second ruling I disagree with is shadow in the warp and pychic powers.
Now we all know that shadow is ment to effect communications on a system wide scale.
But to make it more interesting the made it so it has 12″ range, a foot and everyone cool thats pretty decent effect 3D6 with an average 10.5 even though I don’t think stats effect games I still think thats pretty darn good your pretty boardline passing effects in that area.
Did I say we lived in a mech heavy world.
Well you know what we can do to increase that problem.
Not have this effect you guessed it Vehicle!

Now no one can argue that the tyranids is an accessable army.
Nor can you say that they are something that is extremely powerful.
With both of these rulings fairing on the line of the vehicle heavy mech list guys you make it at lot harder.
These are ment to be the egdes that tyranids have.

Credit where credit is due.
Mawlock brilliant job you have confirmed what most sane people thought.
Prime I am accually on there side with because you have him droping in with the Zoanthropes and stuff like this, thats not what he was made for.
Thats rules as written hammering into intended.
Agree with you guys on the point that is well done from the point that it answered a boatload of questions.

The disagreement for me is on how they handled certain things.
Cause they just gave everyone bug spray, they call it mech.
