Recently watched the
Raid Boss video for the April update. Watching it, I couldn't help but draw some mental comparisons to certain other large dragon creatures from Monster Hunter.

Overall, the dragon breath attacks and AoE abilities looked nice. The only rough area mechanically to me looked to be in the physical body attacks. Maybe it's just cause I'm too used to Monster Hunter now a days, but the physical attacks seemed lackluster for a creature of that size. The body slams to the ground causing large waves were a nice attack pattern, but the small claw swipes seemed really bland compared to the rest of the attack set.
Guess I was thinking it'd be more like in the GIF above where it'd be stomping and charging around the battlefield more, causing more of those players in the back to need to actively avoid getting stepped on. Might just be something that doesn't translate well to the Holy Trinity battle style though.
