If you get Prae hooked you're dead, unless the Prae literally sucks ass. My experience playing it is that 99.9% of the time, barring exceptional circumstance, a landed hook is a guaranteed crit, kill, or cap, while being much safer than Warrior's Lunge.
Of course, this is expected from the T3 evolution of Warrior.
Now, the reason why you're always seeing Warriors comes down to a large combination of things, but I'll list some here that I think are the most impactful (but in no particular order of how impactful):
1) Several good players have taken up maining Warrior, and are frequently doing well with it, which leads to more people trying it.
2) Warrior is the only T2 in the game that stands a chance fighting on the frontline, because it is the only T2 designed with the intention of being able to survive there.
3) Warrior is the only Xeno that evolves into TWO T3s, and if you account for strains, that two jumps up to six, since all the Praetorians play differently.
4) This thread, and people in the Discord, Dchat, OOC, starting to bring up Warrior again, showing extreme levels of salt towards it, etc. are all pushing people into trying it. "Well, if it's making that guy mad it must be fun as hell." Or some other variation of thinking, people are drawn to play it more because of that salt it's generating.
Personally, I think the only reason it's in the limelight now is because multiple good players are running around with it popping 20-30 kills every couple of rounds, which is decent but not significantly impressive. If we're talking purely in terms of the 1:3 ratio of xenos:marines, the marine equivalent is a 10 kill round. That's also not accounting for, in a 30 kill round, a significant majority of those kills will be on the same player multiple times, it's never 30 different people, it's usually 10 or 15 different people killed repeatedly, at best.
I truly believe that if people were playing Base Prae, Vanguard, Oppressor, Base Rav, and Berserker as much as Warrior was getting played right now, you'd see similar kill facts popping up for those castes.

This was as a Berserker like half a year ago, and the caste hasn't changed in pretty much any sense since then. Is it an extreme example? Yes, but 40% of that is definitely achievable on a regular basis in normal rounds.
