Actually, I disagree. While CP may be slightly more important for using the new generic command abilities, subbing in a couple Fungoids ultimately won't help. Two unbinds isnt enough to stop any magic-based army, so thats not worth it. Endless Spells, especially predatory ones, will ultimately be not worth it. Only the CP would allow Fungoids to be worth it. I think a pure BCR list, not counting the Beast Hammer of course, can still be very competitive without spellcasting.
The fact is, everyone knows BCR are underpowered and not very competitive. Therefore, not as many people know how BCR works. They don't prepare armies to deal with things like 4 Stonehorns. Their underestimating alone can be a huge advantage for us.
We can show others, through simple Alpha Strikes and big-@$$ mammoths , that we are a force to be reckoned with, without the help of unnecessary things such as spells.
