I was nudged to toss in my 2c, so here goes

For reference, I'm relatively new to EA; having only played 11 or 12 games with the Tau.
I like many of the changes to the new list. Although I sympathize with those who had modeled up Vespid or Moray, I'm happy I no longer need to worry about how to effectively convert them (and don't have to suffer the raised eyebrows when I announce that this AX10 is going to be subbing as a *insert fish name here* this game). I also like the new Markerlight cut-backs and GM restrictions; in previous games, I always tended to load up on GMs and just fire them unguided ... the cost of getting MLs close was just too high (without towers ... which I had no easy way to convert ÂÂ

) and generally not worth it when the missiles could be delivered unguided via pop-up without fear of retribution and only a slight reduction in efficiency.
I'm a fan of the new Jet Pack rules. I'm not an expert at the nuances of EA tactics by any stretch, but I don't think I used the old Jet Pack rule once. I was always either too close or too far away for it to matter. If you're going to bother making a special rule, it should at least have an impact on the way the army plays!
On the topic of Firewarriors, I was mentally composing a response in my head ... and then I read Honda's post. IMO, that's the crux of it. Firewarriors are not supposed to be good at camping objectives. They don't fill that role in the fluff and they don't fill that role in 40k ... it's one of the things that defines the Tau in the 40k 5th ed environment (lack of a good objective claiming unit) and one of the great challenges of playing that army well. So giving the Tau a bit more killy-ness in compensation for their lack of campy-ness seems to me to be both fluffy and fair.
Perhaps this has been discussed before; what if Marked targets could not claim the benefits of cover? I could see how this could be overpowered in previous versions of the list, but given that Markerlights are now harder to come by (no Markerlights in FWs and no more towers), I think it would be more balanced. It would give well-designed (diverse) FW cadres a bit more self sufficiency if they included a Markerlight carrier. If people started including Markerlights for cover negation, it would be an indirect boost for GMs as well.
Thanks for your hard work on this folks, I'm hoping to get in a few test games in the coming weeks.
