Currently, it works like this:
”Pillar of Tlálocan: Target a location to call down the Pillar of Tlálocan, obliterating fortifications on impact. The statue remains to defend the area with water strikes until destroyed.”
What if the pillar could also heal your own units (just like the healing spring)?
I think that would be really cool 
. What do you think?
I have seen that suggestion somewhere else.
I think it would make sense but it might be unbalanced when available to Quetzalcoatl.
water often has a healing effect so why not since its a more defensive GP of a defensive god this would/could make sense.
i personally think this GP and the one of Xolotl could need slight buffs during vulcano a slight nerf. i get that both tlaloc and especially xolotl myth units (and upgrades?) are slightly to much better but you could buff the tech of Mictlan or the myth unit more instead (i would still like to see Tunkuluchu as the only flying myth unit - at least via upgrade)
Indeed!
Don’t get me wrong, I really like Pillar of Tlálocan. Right now, though, it feels a bit underwhelming. Most of the time, it only destroys one building, yet it can easily be destroyed by ranged siege weapons.
