Whether it's easy to accomplish this quest, which as I remember from the last time one of my characters did it, involves gathering of the quest items on the east coast of the area and your recommendation is to come in from the west side of the area, depends entirely on one's level and abilities when attempting to navigate to the appropriate area to perform the requisite activities. If you are just finding out that you need to follow those directions to access the Swamp of Sorrows, you are probably unaware that Alliance players will almost immediately encounter Stoneard Scouts and Stonard Explorers, marked PVP, patrolling the paths on the west side of the Swamp of Sorrows. If you don't want to be flagged for PVP for fighting them, they need to be avoided. And that's just the first of your worries for taking this path to the quest area. The path soon branches into paths leading southeasterly and northeasterly. The southeasterly path will take you smack dab into Stonard. If you get too near it one or more level 65 Stonard Grunt (Bosses) will come out and attack and you'll be quickly dead. Again if you attempt to fight them, you'll be flagged for PVP (and dead). As soon as you spy it, detour to the northeast. The northeastern path leads into Fallow Sanctuary. which you'll also want to avoid as you'll get mobbed on your way through. So in either case you will be traveling off of the pathways and across country and likely agroing one battle after another with Swamp Jaguars, and Sorrow Spinners in the jungle, and Sawtooth Crocolisks, Snappers, and Tangled Horrors in the waterways. You may encounter the Pool of Tears in east central Swamp of Sorrows, which is generally quite safe to swim across the top, skirting the Temple of Atal' Hakkar in the center of the water. Once you reach the Misty Reed Strand, which forms the northeastern coast of the Swamp of Sorrows, be careful of the level 43 Monstrous Crawlers if you decide to attack them, as they can be problematic for lower level characters on this quest. So bottom line is if the quest is red or orange to you, tread very carefully when going this way. If it's green or gray to you, then it should be relatively easy to get across the area (and you probably already have the map filled in for this area, having been there before...).
