I for one don't like it abit. For starters they have to make them lvl 70 epic X4!! I mean come on What fun is it if you die in 1 hit from these mobs. About the only areas you can go to without a raiding party is pretty much the little towns outside of the main city.
And to top it all off I dont' see how you can get the update for Reaching blade of the assassin thanks to this update. There is a lvl 66^^^ guard outside of the inn, and there is a lvl 70 epicX4 encounter which includes a guard and 2 dogs on each side blocking the route that goes near the tavern. None of these mobs roamed I waited quite awhile for it. I would imagine anybody even in there 60's could die easily from 1 or 2 hits from this encounter, especially since being a SK its going to whack you with a insane harmtouch being epic and all.
Also North Qeynos is now full of lvl 70 epic X4 guards that roam all over the place. This doesn't include the roaming lvl 60ish and lvl 50ish guards as well. So its not going to be a walk in the park for evils either. However at least Qeynos is Doable.
I had actually put off doing that quest for this patch. Should have known SOE would ***** it up and make the towns more impassible then ever! And to boot the ones that are actually heroics are also way underconned. I can normally solo a lvl 40 or 41 green mob, however I started in on a lvl 41 guard ^^^ and it had a TON of hitpoints. DPS wise it was no different then yoru average 41 mob, but I know it had ALOT more hitpoints then it should. Of course I haven't killed any lvl 41 heroics since patch, who knwos maybe they snuck a nerf in on us.
