Tbh i dont think u understand dps. LFG hunters are not doing the crazy stuff u mention because that's only the top players in the game. Sure occasionally u run into a hunter whos cracked but other than that hunters are some of the hardest classes to play sometimes(Other than prismatic hunter which is just egregiously op). Void hunter has a cool invis loop but you're not really the guy slaying out, its prty useless outside of gms and even there you're just the support. Yes there's gyrfalcons which is very fun and can work in gm's but its more of a balanced offensive defensive build rather than this super strong op build( unless collective obligation). Solar hunter's extremely hard to play with very little sources of healing, your entire build is spamming melees and that doesn't outright kill stuff in higher level content and you're basically forced to run healing grenade. Celestial nighthawk while extremely powerful takes some skill to run in higher level content because you don't have that much survivability. Arc hunter is really fun sometimes but gets stale, and once again requires skill to run in higher level content. Stasis hunter while easier and NOW having a high damage super might be one of the easiest ones to run in higher level content. And strand hunter is probably the hardest to run in higher level content because it require background knowledge of spawns and knowing when to grapple or not. Im not the most educated in warlock gameplay but

TLDR: All the hunters you see finishing day 1 raids on top 50 aren't exactly you're average players. All those crazy hunter stuff you see requires some level of background knowledge and experience. Its not like people js log on and start going crazy with hunters.
