Read this post for the reasoning.
Im torn on this after seeing both sides of the coin, my morals say abolish it but logic dictates it is now a necessity.
On the one hand, we know it can be done, however taking what i saw on gaia about 1 year after the agreement, people became nigh unstoppable, people with  on their armour will not die, if this is a no noss agreement i would suggest that
1) KOs be kept
2) Only defensive nosses are abolished.
The reason being when everyone has  on everything thats 100 abs on evey peice of armor.
500 abs + 100 (for melee classes with a shield)
Add to this the HP lapis that many will have linked and when you take out 500-600 damage people simply don't drop, especially the ratio nubs. The attack power at that level simply does not exists. It turns out you NEED the extra attack for pvp simply to exists at that level.
Its for this reason i would suggest not abolishing all noss and rather focus on keeping a few crucial key ones. Or you will find pvp stagnates very quickly when nobody dies.
I would still allow KO and one or 2 minor offensive nosses while abolishing all defensive nosses. Otherwise the ubers will simply not die. Ask anyone on gaia before the server merge. Extra attack power is needed at that level for back and fourth pvp to exist.
Just my 2 cents.
I Guess by using this logic i would have to vote for keeping noss simply because abolishing it all would do much more harm than good (this coming from a vivid anti noss activist) but that is what Aeria has done.
Fyi not all of us in 15 are full worship, not all of us have a dread or herioc piece and finally not all of us are  I can assure u its not a whole lot of fun when a maxed out player is nossing and going after the easy kills. Maxed out ppl wont die regardless of noss being allowed or not, in my opinion, or they'll die very hard and the other side wont even bother with them. I dont mind nossing, but ppl dont know how too use it, so I'll say 12
The question everyone must ask is "what if the alternative is worse" You will nerf ubers a little, yes, but those that ARE in heroics worships dreads ect ect will still carve through you, its about them dying more, not you dying less, it needs to be, kills are kills. I saw and experienced this firsthand on gaia, i went in with a  wep  on my worship armor and was still completely ripped apart by ubers that were not nossed.
As i say its a matter of attack damage, you need the extra power there or the immortals will still be immortal.
But its up to you, i'm just throwing that out there, i don't play anymore so i can't really have a say.
