New units. Their discussion and selection of upgrades.

In my opinion, Crystal Dragons only lose out in terms of appearance, and it's a pity they removed the immunity to Earth.

There's definitely nothing terrible about this, because few people attack dragons with Earth Shock or Stone Spikes. So, it's not a big deal, and the appearance isn't that important. However, the loss of guaranteed double attacks and the replacement with a prismatic attack is something to consider. What's better: guaranteed double attacks, or risking a prismatic attack? In my opinion, the latter is better because everyone knows about the dragon's breath and doesn't place units in pairs, while the prismatic attack can hit any unit, even those standing behind.
