Okay so just looking to see if anyone's had a similar experience to me...let me explain my circumstances.
Im a 4.5k GS DK tank, frost specced for damage reductions including IFP and I have 32k health, 28k armour and 553 Defence Rating yet when I'm in dungeons I just seem to be taking masses of damage like I'm getting crit. In Nexus the other day I was killed by a pack of four mobs in the crystal grove (correct name?) which seeemd odd when the healer and rest of the party were 264 iLvL geared and I was popping everything I had in my arsenal to reduce damage taken I think I had about a 70% damage reduction at one point (including reductions from armour) yet got destroyed like a punk.
A couple other people from LFD mentioned they'd experienced similar situations...but yea has anyone else encountered this I had attempted to contact GM's but have had no response and daren't try the official forums for obvious reasons of not getting any actual answers just the usual trolls. Now at the moment my character on armoury is not in his tanking gear so I'll put him in it when I get home and post a link here for you all to see...but for now it's back to work with me
