Having a flip through th Errata and FAQ I'm noticing they've cut chunks of fluff away from the Wargear Entries. Case and point, Bonding Knives were nearly 12 lines of paragraph, now condensed into an easily understandable 3.
Something like that makes me think there may be a lot of Background re-writing going on in Ye Olde Nottingham City. Aun'va guide us
However, that despite the reduction in fluffiness, it means that Tau's uber-newscience-xeno-tech, now feels more approachable. I'm going to go ahead and say Tau would have been a lot easier for me to understand all those years ago, if the wargear entries were this clear (garaunteed, I still would be the pants gamer I am today).
An interesting point is that under the new rules, Decoy Launchers are worth their points now, as vehicle damage is now on a single chart, and its entry no longer specifies a "Glancing hit" as it did before.
Interestingly, with the change of Target Locks no longer having affect, and combining it with the new Vehicle damage rules. a full unit of Pathfinders, with three Rail Rifles, may be a good choice. three glancing hits could reduce the target vehicles HP, whilst the ML hits increase chances that the next volley of fire against it will take it down.
This makes me think that Tau will work supremely well with co-ordinated Tactics, possibly more so then other armies due to our high Shootiness.
Seeker Missiles seem unaffected if the Vehicle is Shaken/Stunned.
A note on Vehicles Gun Drones and Victory Points:
They DO give VP to the opponent if they detached from the vehicle, before being destroyed.
They DON'T grant VP with they are still attached to the vehicle.
This makes sense, as after detaching, they are two seperate units, whereas before, they are singulare. So don't detach you drones, unless you have to.
Thats just my thoughts whilst reading through the Update in front of me on paper. I printed it off you easier ref.
