I just made a nice longsword, so I changed to finesse (90) and rest into longsword and quake.
longswords are imo not that great. they neither provide the speed of daggers nor the aoe damage of greatswords.
quake is in the same boat: low range and if you should actually be able to chain 3 quakes with all of them dealing decent damage you only get a 40% chance to stun (the stun you would really like to have WHILE casting that shitty thing) - just swinging your greatsword with an ice and lightning enchant (and at best the chain lightning ability) deals more damage, staggers the opponent more reliably and is far harder to interrupt.
I'm pretty sure i'm not unbeatable atm, but 14 bandits my level not being able to even get close to me is much more epic than 100% physical resistance, cuz I would chew right through your defense bub, with my 122 piercing damage daggers 
I have 40% DAMAGE resistance, I don't even care at this moment about magic damage or weapon damage, cuz with 40% damage resist, and 6% chance to evade ANY attack (soon to be 12% which is op) I'm going to lay waste to anything and everything.
you could scratch my back with those daggers. not only do i have 70% piercing resistance (~45% is universal damage resistance, which will increase once i manage to acquire the required pieces to craft a new item) but also a shitton of armor and my breastplate has a +60% chance to stun on hit gem crafted into it

When I kill in sneak attack, I deal ~80k damage, might/sorcery specc doesn't even allow that.
while might/sorcery doesn't have the instant kill move out of stealth i believe it has the higher sustainable damage potential.
in the might tree you have +30% through weapon mastery, +60% vs. stunned enemies, +100% max through battle frenzy, +15% speed (which more or less equals +15% damage) through celerity and 20% chance to reflect incoming attacks through vengeance (i loled so hard as a troll knocked himself out on me)
in the finesse tree you have +30% through weapon mastery, +30% critical damage through blade honing and +150% damage and +60% critical damage that only works if you attack from stealth.
You move (warp?) through your opponent thus dealing minor damage and automatically face towards him when the move is finished, while they have their backs against you. if followed by a melee attack you will strike him with you palm and stun him for a short while. This is very useful, because then I can charge up my faeblades attack without interruption.
what interests me is whether you can "warp" from a decent range or if you already need to be more or less in melee range.
basically if it is worth considering dropping the might/sorcery "blink/gravedigger combo"* for lunge.
*slightly out of melee range you blink through the mob right behind him, activating gravedigger thus doing aoe weapon damage and pushing the mob away from you just far enough that you can blink right behind it again (the mob has turned to face you in the meantime) repeating the process without the chance for it ever hitting you.
