Forge World Focus: Mars
The situation they describe is how I feel the meta is shifting. They talk about a large number (20) of elites being buffed by a character. Having lots of expensive units is too easily countered in 8th. If the enemy dumps a troop blob on an objective those shiny High Strength High AP weapons suddenly feel very ineffective.
If you're looking to build a list to counter the conscripts I think the most competitive option for tau is a Double battalion + outrider. 10CP and enough drones and firewarriors to rival their army for models and provide bubble wrap for your commanders and their S7&8 weapons.
