Even while wearing chainmail or even transitional you can be one hit but throwing lances if you're moving towards them. They look ridiculous, five foot long lances that do ridiculous amounts of damage, are extremely accurate and even do bonus damage against shields. Javelins and throwing spears/jarids are a bit OP as well, but not as ridiculous as throwing lances. I just think they should be removed from the game. Who's with me?!?
One hit? Yes. Just about everything else you said was false. Not going to bother reading the rest of this whine thread. Throwing isn't OP. Throwing got nerfed HARD in the big patch, and pretty much sucks now. There are just so many more throwers because it no longer pays to be a specialist, and throwing is an easy fit for a sidearm to a melee player. Return the WPF costs to what they were pre-patch, and you will see less ranged spam. Without the bonus WPF from retirement, the old WPF costs would not be imbalanced.
On the topic of lances, they are SUPER inaccurate, even with lots of PT and proficiency. The cost is absurdly high, and you only get 2 in a stack. So yeah, they one-shot people in mail, if you can manage to hit them. But hitting them requires that you use the force, pray to all the gods of all the religions, and pay off game developers.
I'm not a thrower, but I had a pure thrower when the patch hit. I stopped playing a thrower because of how badly they ALREADY nerfed throwing. When I get hit and killed by a throwing lance, I simply smile to myself, knowing that the next 10 times he throws at me, he will likely miss his mark.
