Reading the creature guide and playing with these creatures has me wondering what the Alpha Giganto's role is exactly? It's far less powerful than the Sasquatch/Yeti, cannot be brought into the boss arenas, and is lacking the ranged attack (being added in the next patch according to Psycho's change notes).

Pros:
-Insane health and damage scaling, can actually invest into health for growth once tamed, unlike Alpha Giganto. (My Sasquatch has 100k Health and 620% melee after being bred/mutated a bit)
-Far more common, in my experience
-Tames on Veggies, no kibble requirement
-Appears to get far more than 20% health boost from a full 100% imprint bonus. In fact it's almost double on mine (Starting health 12k, 23k after imprint)
-Great Torpor and low level bulk, useful even at level 4
-Strong right click rock throw, bypasses "projectile immune" enemies like Skeletals, Chieftains, Bosses, etc.
-Allowed in Boss Arena, dominates bosses
-Turret Mode makes it a top tier base defender

Cons
-Poor taming effectiveness from Veggies, Xeno Kibble doesn't work, Titanboa Kibble doesn't work.
-Large Torpor pool and high damage makes it difficult to tame early game. Seems balanced.
-Helmets break quickly in EC in general, inability to wear Prime helmets gives it very temporary effective health. Again, seems balanced.

Pros:
-Tames with Titanboa Kibble, good effectiveness if you happen upon a high level.
-Can throw the player, not sure if this is a pro, hardly use this feature

Cons:
-Extremely Rare
-Lacks ranged attacks (being fixed next update)
-Terrible HP scaling, results in bad bulk due to aforementioned helmet problem. Perhaps give them the ability to wear Prime helmets to act as a "saddle."
-Highly aggressive and difficult to tame early game, though seems like an early game Alpha. Like all wild alphas, it Maim's/bleeds, wearing you down eventually regardless of bulk.
-Moderately difficult kibble requirement
-Not Allowed in Boss Arenas

Prime Helmets and shrinking their size to allow cave access could give them a niche/edge vs their beefy counterparts. If anyone else has found a use or advantage for them please let me know. Allowing them in Boss Arenas and not allowing Sasquatch/Yeti in seems like it could help as well.
