I'm going to try and offer a silver lining to these changes (and copy/paste this to other races aswell)
Target Locks were 5pts a piece. Taking Carrelio's description of a list (assuming three units of BS, and 3 DR units) thats 30pts now loose for other things in the army. We may find that certain lists work better, as other options are either better fit, or are no-longer useless.
Thats the silver lining, now heres something to think about (the salty sugar in the silver spoon).
We curently don't know what a 6th Ed codex is going to contain, norhow it would be written, nor which race it'll even be for when the first comes out.
Edit: Did anyone else notice that Farsight now has one of the strongest power weapons in the game... since it wasn't FAQed it still just straight up ignores armour. Take that marines!
I noticed that the moment I saw some of the rules that 6th came out with.
5 S5 I10 attacks on the charge, which are equivelant to Monstrous Creature Attacks? Yep, sounds like Tau
