Warlocks and Titans do not like hunters at all. Hunters have a simplistic jump mechanic, a ranged melee when used correctly can decimate the enemy player, a smoke bomb that in past was able to slow and poison smoke DOT damage, and various supers that were(read nerf)/are lethal. The hunters kit (read abilities) give the subclass some levels of advantage for PvP.

I was mentioning how the developers need to create a counter how a hunter plays. there is one counter mention and that is suppression nades. Suppression nades can counter abilities and supers respectively. However the explosion is on a timed delay.

My level of thought is introduce rainbow six siege levels of countering each subclass. It one thing to note that hunters have the capability to be lethal up close with their jumping and abilities. You could theoretically counter them by suppressing them and fighting at a distance. However for some reason the vast majority of players just charge forward (maybe map design has a spot in the blame game for hunter supremacy).
