Guild Wars 2

PVE gear (for WvW) should be attainable through spvp, but definitely not in the way you are suggesting. As others have pointed out most of your suggestions would encourage bad gameplay.

The only “fair” way to reward such items is by points accumulated or perhaps matches won or current spvp titles/ranks unlocked. Sure there is an element of grind to that, but pve is also basically about grind and rewarding players for long participation in the game is not a bad thing.

In fact this is the only game where my dedication to the game from launch and many hundreds of hours playing (spvp) rewards me with virtually nothing in game. That is one of the biggest issues with the spvp part of the game, in addition to lack of game modes. The issue is compounded because WvW is the other pvp part of the game, but dedication to pvp (in spvp) does not give any heads up into that part of the game.

Basically, playing spvp is just a mini game totally cut off from the rest of GW2 and you actually handicap yourself by playing it for extended periods.
