I've only ever played on 5 Mir servers; official Mir2 EU, official Mir3 EU, official Mir3 Global, Acem2 and Chronicles. Only one of those had no PvP drops on and on that server I experienced more PvP than the other 4 combined.
PvP drops in MMOs is an outdated concept that today only works in a small number of niche games. It does not encourage PvP, It only fosters toxicity in the community. The fact that "PK" has been mentioned 71 times in this topic and "PvP" has been mentioned 9 times shows the mentality of the Mir community.
Ruining another player's enjoyment by ganking them and taking their items should never be an incentive to PvP and if bragging rights, boss kills and leveling spots are not enough of a reason to kill an enemy then consider K/D ratios, scoreboards and honour points.
You could compromise and have a few powerful items purchasable and upgrade-able with honour points that can be dropped in PvP. However, it would need to be restricted to only a few items slots (maybe even only 1 or 2) as to not detract from the need to gain items through PvE.
