I have been trying to do some exploring in Tyria in Hard Mode and warped into Grendich Courthouse a few days ago.I really felt like sinking my teeth into some serious Charr ownage..yea.
There are mobs of 4 Charr per group when you exit the Courthosue into Diessa Lowlands.Your party is limited to only 4 teammates by the way.Everytime I try and kill them, my team of heros and I, are getting annihilated.Character swaps,weapons and skill swaps,crying like a baby..we get punished.I've tried a few different builds for myself and I must admit,the way I have Koss setup works extremely well.Dunkoro and my Fourth are probably my problem,but I was curious if:
A)Anyone has tried these mobs in this particular area in Hard Mode?
B)Help me with Hero builds or suggestions,because im at a loss.
Here is me and my Heros:Please Note..Dunkoro now has the proper Runes to accomodate his skill setups and I am well aware that Norgu has no offhand,I've been swapping characters between Norgu and Master of Whispers and have found dramatic differences in progress..anyways..help.
Myself:

Koss:
NOTE:I have set Koss up as an Earth Tank,my basic stratedgy while using Koss is to target whatever melee Charr spawns,IE Axe or Bladestorm,Hamstring will always be the first thing he activates and his longevity is amazing.

Dunkoro:
NOTE:I have setup up Dunks in Defend Mode and have swapped his Elites from Spellbreaker to everything else.I have maxed his atts in Protection and Divine and using him to shield Koss as well as himself and whatever else he can in the backline.

Norgu:
NOTE:Norgu wasn't my first choice in my fourth toon slot but I've worked him a couple times as an Air Spiker,forcing him in attack mode to target the Chaot that will spawn.I'm finding him effective in shutting down the Chaot Charr,originally I had Master of Whispers as a BR/Blood Sucker.

So I'm finding Norgu really squishy,he's really effective at shutting down the Chaot which was a big plus and something i wanted to do,but I find that even the Shaman and Hunter (or Necro Charr) will be able to decimate my team,Shield of Judgement is a pig sometimes and Koss will have a mind of his own and Leeroy.The Hunters damage and speed is rediculous.Its also really fun when a Flame Wielder spawns,and you get rezzd after being slaughtered,only to be spawn killed by Meteor Shower , over and over.
How is a team of 4 effectively able to beat these mobs?I HAVE beaten one mob here and there but its not "fun",challenging yes..but I'm not progressing.
I'd also like to say that My skills posted in this picture are not in stone,I have tried other builds,but I'm trying to generally concentrate on slowing the melee enemy Charr for Koss to inflict some damage...but like I said the damage thats being dealt to myself and the backline is tremendous.
