Well, that are two very different animals.
Behemoth needs some mobility buffs, true. But two unbalanced things don’t make a balanced monster. You cannot buff one aspect to address a totally different problem. That’s only gonna make him less reliant.
Teams who don’t know how to fight against the advantageous aspect (let’s say the “tongue grap, fissure, heavy, roll” combo) get wrecked and teams who know how to fight against said aspect and how to exploit his disadvantageous aspect (mobility) will wreck him.
Another example is Kraken. He has a low W/L ration on the low tier. So they tried to “fix” the problem of him being difficult to master with increasing his burst damage. We all know how that turned out. ^^
Wraith has trouble downing s.b. because it has only one burst attack (Warp Blast) so they buffed its melee range and tumble towards “Well I can’t even move once it starts meleeing me”.
So, please fix the bug with his traversal audio AND make him more viable. Don’t try to band-aid one aspect by aggrevating another problem.
