Then you are a true man, for you know your only weakness.
Actually that sounds more like you pressed enter too early
All the time i see I think, i think, i think...yeah, good to have opinions and stuff, but in this matter, it is really hard to see other side of the fence. Either you do use those knockdown weapons and you do not want to see anything happening to them (and god, i do remember morningstar with crusthtrough and other suff) or you are a guy who doesnt like to be knocked down in his heavy armor by a freaking peasant with hammer. I get it. I am on both sides, when i level up, u use mostly blunt weapons, on higher i am getting used to play with Bec in secondary, man, that is lots of fun. And even with my 8 PS i do not knockdown everytime. And yes, even i do get pissed while knocked down by some shitty low tier weapon in hands of a paperman. But guess what? I got used to it, shit happens.
Saying that randomness is bad for pvp environment is bullshit, it adds a little spice up to the mix. Still i do think that high tier armor should really do something more than just make you feel better about yourself, when we speak of knockdown.
Not to speak, most of the KD weapons are quite fast too, so they are really too good as melee sidearm. I do not mind archers being somewhat able to defend themselves in melee and land a hit or two, the bitching that archer can never compete with 2h/polearmer is unnecessary, as they usually have quite high athl and light armor, hence beter maneuverability. Add this to high speed knockdown weapon and voila, you do not even fucking need any points in melee skills to do well (and yeah, i do play alt archer with mace, so i know what i am talking about). The athletics by itself gives you quite huge advantage on slower target. You can dance in, hit, dance out of his hit, repeat. And take into consideration that every hit he makes can have quite some speedbonus=dmg=knockdown chance.
Id say knockdown weapons are fine, but not as melee sidearm for ranged
At least i would remove knockdown from all 0 slot weapons that have it (if there are some more than hammer).
