No, we rolled a 6 and got a semi-intelligent storm that won't mess with our own projectiles and soldiers. Again, I mentioned it: Communications failure. I did not explain and emphasize what was important about the plan, and so we got something different.
My problem is that you're not proposing to do anything about their artillery, and I'm not proposing anything that completely nullifies it. You're proposing that we trust in 100% reliability of your spell, because if we get anything LESS than that we're going to get killed in huge numbers. Cannonballs firing through ranks of soldiers like this can kill upwards of 40 men per shot.
I'm not trying to convince you that my spell is useful, we're all smart enough to understand that both spells, theoretically, might work. However, the problem is that practice says that marching in columns towards enemy artillery is voluntary suicide. The six was, effectively, wasted in making the storm intelligent.
That said, on Discord, SMMI has had some fun ideas about what you can do with intelligent storms. Namely, storm elementals are probably two turns out. Next turn we use another design to separate further our wizards from the storm/perfect our control, and then the turn after we design ourselves a spell that allows a mage to summon and control what amounts to a swirly troll-shaped mass of wind and lightning. Which will be extremely fun.
