Fighting happens in clusters. If you have knowledge of the quest, then you know when and where those fights will happen. The vast majority of groups are going to zerg, so anticipate this and move ahead of them. Leave while the group is finishing off the last mob or two and start heading to the next fight in sneak mode, building up measure the foe as you go. Get to the next encounter, wait for the group while selecting a high fort target to take advantage of the bonus DCs from measure the foe. More than likely the group will have caught up with you right about the time you get there, so choose your target quickly. Move into position, assassinate, then drop out of sneak mode and go attack whatever mob the group is currently beating on. Select your next target while dpsing, a lower fort target since you won't have measure the foe, drop into sneak mode as assassinate goes off timer, get into position, assassinate, then go back to dpsing with the group.
If you fall behind the group, don't stay in sneak. Catch up to them and just don't count on having measure the foe. For a large percentage of content, measure the foe doesn't matter anyway. It's only the highest level content where you really need it and want to take advantage of it. Where it doesn't matter, just zerg right along, dropping into sneak only to keep assassinate on timer.
If you're sitting in sneak mode all the time doing nothing but assassinating, then you're wasting a huge amount of potential dps. You have to be able to switch between assassinate and dps quickly and effectively to utilize the build's full potential.
Getting into position requires knowledge and awareness of mob movement and attack patterns. Archers, for example, stand in one place for a certain period of time, then move a short distance and continue firing. If they are being attacked in melee, they will move back away from their attackers. If they are not being attacked, they will move to the side or forward toward their target. If you're paying attention, you will know how long they've been standing in one spot, how soon they will move, and where they will be headed when they do. All mobs follow some sort of pattern like this. If you know it and are paying attention, then you end up in the right place at the right time and they never see it coming.
You also have to be aware of mob attacks so that they don't knock you out of sneak. Don't cross an archer's line of fire and avoid melees' cleave attacks, for example. Altogether, playing an assassin effectively requires knowledge of game mechanics, quests, and the immediate situation, taking all of that into consideration and then acting accordingly. And it all has to be done quickly if you want to keep up with the group.
It's this very dynamic and skillful playstyle, especially in a group, that makes assassins a unique build to play. Under no circumstances should this be made easier because this is exactly what makes them so much fun to play. If you're good at it, then you're as deadly as any necro caster, as well as many other builds for that matter. No, this playstyle is not newb friendly because it does require a great deal of knowledge to play effectively. No, it is not a playstyle that is widely enjoyed by a large percentage of the playerbase. But it's the only build that plays this way and is greatly appreciated by those of us who do enjoy it. And if it's a playstyle that appeals to you, then you will learn to be good at it.
