I still manage to have a good winrate with behemoth (won 7/10 games ive played with him) but hes not very fun to play. His traversal is buggy and ill suited to half our current maps and his feels sticky with how long it takes his abilities to cast. If you do want to play him however,
2 tongue grab, always and forever. As behemoth you cannot chase hunters around, it just wont work you have to bring them to you. Take 1 fire bomb and fissure for maximum damage and cc potential. Rock wall doesnt do anything for but “maybe” let you eat in the dome. Its ideal against val/hank teams but its buggy and to get proper vision blocking height youd need to invest too heavily.
You wont get any strikes stage one unless your opponents are asleep and you sure as shit arent going to run around fast enough to get stage 2 without being domed so your best hope is to juke. My favorite path on my favorite map is weather control, take the left path with the canyon strider, follow it and eat the cats, take a right and eat another pair of canyon striders and another pair of cats. At this point theyre going to hit the UAV so walk a bit torwards the beach and sneak back into the cave. If they fall for it, great, youre on easy street and might actually get to stage 3 this game. If they dont great youre probably still going to hit stage 2 and youll be fighting in an area that favors you.
The combo that youll live and breath is Tongue>fire bomb in front of you>fissure the problem is that the tongue only stuns for 1.5 seconds, past that and theyll just jetpack away and you cant do anything about that so after wounding somebody you want to kill youll have to follow them into whatever traps the hunters have laid for you. Behemoths combo is a 100-0 but behemoth telegraphs heavily and cant really close the gap. As a side note, unlike other monsters youll probably want to pay attention to the assault, Hide in a corner and combo them when they enter, make them pop their shield. Behemoth more than any other monster is capable of destroying somebody with a medics attention. Especially somebody right next to him.
As far as perks go, the new perks have been a blessing to him. Im partial to bronze brawler, silver insatiable hunger and gold cooldowns or damage reduction.
