So what about this. Death in WvW will handled a bit differntly. Death will not result in equipment damage, rather it will have a debuff effect. (call it Moral Lost, or Death Sickness, etc). Similar to that of GW1, on each death, you would have a say (-5% to -10%) on all stats and HP (number could be adjust and balanced, here use are just an example). This stacks. This debuff effect goes away after a while (say 10-25 mins), but can also be instantly remove by an NPC at the camp (at a cost of some copper/silver per stack). The affected time can also be decreased by finishing objective, help rezing other, or making kills. This affect is remove once out of WvW, however, returns when return back to WvW (within a 24 hours). (this is so to avoid people resetting themself by just enter and exit).
I think this might help to make WvW more attractive and competitively, while still retain some of the desired usage of repair cost in game.
edit: increase the suggested time of the debuff.
