Is that he is a tanky monster that isnt all that tanky. Oh I’m sure he can take a hit better then Goliath and all that jazz but the fact is the other monsters are supieor because they can actually move around and dodge incoming damage while Behemoth for the most part just has to sit there and take it.
Not being hit will always be better then being tanky.
Its why Wraith, Gorgon, and even Kraken do so well. They can play keep away all god damn day while doing plenty of damage and taking very little in return.
His lack of mobility also makes him incredibly predictable to a Hunter who knows what he’s doing. Giving Behemoth very few paths to get around. This however is unlikely to change because its part of his gimmick.
The second reason is because Behemoth telegraphs literally everything he does. Goliath wants to breath fire? Instant fire. Gorgon wants to vomit like a frat boy? Instant disgusting. Kraken can fire out sonic booms and banshee mines like they’re going out of style. Wraith has quite a bit of telegraphing but its no where near as long and loud as a Behemoth.
The reason this is possibly his biggest weakness since the hunters are mostly likely always going to take every little speed and jetpack perk that comes to them. Giving them plenty of material to just avoid everything the Behemoth has.
Now I actually have a suggestion for Behemoth. If Behemoth is destined to be a big slow piece of stink then use it to his advantage. Combine his Wall ability with his Lava Bomb and give him his own little death arena ability.
“What do you mean an arena style ability?”
Think Jarven from League of Legends or Odin from Smite. He plops his fat ass down and creates big fiery crater that does dot damage to everyone inside of it. Then the Hunters have to either make the choice of dealing with the fire(and the big angry rock asshole) or fly over the walls to get out. Behemoth gets to keep his tongue grab and earthquake ability. He would just need a new fourth ability to help keep the Hunter’s stuck in his little realm of pain.
“Sounds over powered”
It does until you consider the idea of Torvard, Hank, and Caira bombing the shit out of him in his little crater from up on high. Im sure there’s a trapper who could take advantage of that too… Abe maybe?
Anyway. these are my thoughts on what is wrong with Behemoth and how to possibly improve them.
