Derailment

If you are having difficulty getting 100% completion because of the mobs, jump into the water.

The ships around the dock can be sunk by clicking on them for 6% completion a piece, they respawn quickly, and aside from the very occasional Hunter's Mark that will target you, there are only a few scarce level 93 fish mobs that won't really attack you.

It's a boring, but much safer way to finish the objective if you are undergeared.

If your ilevel is less than 640 or you happen to be a squishy, plan for an interesting and unpleasant slog. Seen Edge of Tomorrow yet? Once you've done this regrettable exercise, you won't need to. It's WoD's version of Edge of Tomorrow. Multiple nasty, repetitive deaths followed by blessedly-short trips from the GY only to discover you can't rez where you died because everything respawns in nanoseconds and you can't get far enough away from the orcanators to avoid being back in the middle of the fight. So you just get to repeat the whole thing from the beginning again. But that's what you wanted, right?

Did I mention that you can't loot the corpses because they've despawned? I love the concept that every so often you're tagged with something called a Hunter's Mark, which means the guys flying around will throw something at you that hits for some amount of damage (it's not consistent) but you have some number of seconds to run outside the red circle. You learn this quickly, because squishies can't fight with one or two orcs and survive a hunter as well. Of course if you're in a fight, with your back to a piece of the scenery, you can't run anywhere.

Except sometimes the timing is not consistent either; sometimes the hunter strikes immediately, and if you're in the middle of a fight, with no armor (cloth armor is for decoration only), you get to try to rez yet again. The Spirit Healer's name is Hilda; you'll get to know her pretty well. Don't accept any of her offers to play cards and you'll just have to get used to her smirking "Haven't seen you in a while....not." Oh don't forget - each successive rez means the next one takes longer, for some reason no GM has ever been able to explain. I think it's a bug they can't figure out. My last rez before I threw in the towel was two weeks, four days, 3 hours and 41 minutes.

But don't worry, the rewards are designed to cover a consistent 10% of your three-digit repair bill. We like that kind of predictability. Console yourself with the fact that the plate guy who turns away from the screen to answer the phone will have a four-digit repair bill.

Didn't like the first half-dozen deaths? No worries, you can just skip the whole thing and go right to Tanaan, where all your friends are. Oh, right - you can't do that; I was just kidding.

I guess we're all Death Knights now.

The explosives nearest to the Alliance base is extremely difficult to get, even if you can fly. Not only is it far off the beaten path to the west, it's guarded by two stationed orcs and a freaking ogron, assuming you don't aggro the pathing orc, or time it horribly and have the pathing ogron from the north sneak up behind you. ONLY DO THIS IF YOU WANT A CHALLENGE.

However, you can instead take the explosive set for the Horde-side quest.

If you can't fly:

Once you get the detonator at (51.42, 14.31) jump into the harbor and swim to the rope ladder at (54.10, 17.13). There is an ogron that paths here; you can get past once he gets all the way west and stands there. If you want to be extra sure, you can wait or follow him to the east and he'll turn the corner to continue on to the crane.

Continue on past Yrel and the train to the end of the tracks and just around the left corner (to the west), where the explosives is guarded by a single grunt.

There is a rope ladder at the end of this dock, (55.49, 14.80) that you could use to get here, but unless you have a reliable stealth ability, you will have to fight several mobs at once.
