I hate to say I agree with W, just on premise, but honestly he makes some mighty fine points. I don't have a single count on any of my accounts, but it really irks me the expectations of some players here in an MMO open world game.. You are hunting dungeons for large amounts of loot, solo on templates not built for surviveability, then complaining with a few PK's run rampant through the dungeon.
This is an MMO - if you want to farm solo, expect to die sometimes, join a guild, hunt with friends, it's far more efficient anyhow with all the special attacks that lend to each others normal attacks. On top of that, use voice, co-ordinate, fend off the PK's, or learn to block PK's, and let your gold mule get out alive with all your loot. Take some bloody surviveability skills, wrestling, bring the right supplies, potions, pouches.... If you have magery, keep your reflect, and protection buffs up...
But for the love of god, don't do the bare minimum and expect to have maximum results...
I am all for creating some ability for PK's to have to fight their way out, removing exit gates for them, that way you can come back with PvP chars, or call in a hit squad to stop them and potentially get your loot on the way back out... but we all have to do our part first, and be prepared for this, PK's are not new to UO, we should all have expected this.
