So, being a Tauist and Commorite at the same time, and hating all things imperial look a good xenos should, I am always looking at ways of combining these two things to cause misery to the Empire of Man. Hence, without much of a segue, I am looking at the formation options instead of running allies mostly because of the allies tax.
The Tau Cadre Firebase (riptide and broadsides) looks like a lot of fun to add in to bolster our tank busting capabilities and basically to draw fire away from our squishy units and focusing on what we do well which is kill stuff up close. Obviously it is a costly addition (600 odd points) but locally we are playing 1850 so I think its worth it.
I see it looking something like:
Baron 105
Wyches in raiders (3 x 10 with HWG)
Hellions 10 +
Reavers 9 +
Beasts as big as you can fit
then add the Tau. Would need to look at points but what do we think?
On top of that, what formations are likely to come down the line, and will we even see one or will it be held off until we get updated? The eldar ones look nasty as well so there may be options there. The other options are of course with stronghold assault, chucking down LOS blocking scenery for cheap, as was stated in another post.
