Today the random daily heroic I completed on Wranngar was Halls of Origination. As you might have noticed I said completed. The first one I was in for my random daily was Deadmines. Deadmines is a tricky one and I would say the second hardest heroic after Grim Batol.
I got in to Deadmines right after the group I joined finished downing the third boss, Foe Reaper 5000. I figured it would be a pretty easy 70 valor points, boy was I wrong. I noticed in the very first fight that the tank, a Deathknight, was looking kind of squishy. The Healer had 103k mana using a flask so I figured we would be ok anyway. Wrong again. We made it through the trash between Foe Reaper and the boat without too much difficulty, but when we got to Ripsnarl, the next boss, things went downhill fast. The Healer was running out of mana about a quarter of the way through the fight, which tells me he had very low Spirit/Regen, I ended up innervating him a few times but it was not enough. To make a long story short we wiped on Ripsnarl 5 times before I finally bailed. I was doing 12k dps which was double what the next highest person was doing, we just didn't have the dps to get him down. Funny thing is we came the closest to getting him down on the first attempt.
After I bailed out of Deadmines I requeued and got Halls of Origination. Once again I didn't get in at the start, I got in right after the first boss. I figured that was from someone either getting what they were after off the first boss and leaving or not getting what they were after off the first boss and leaving. This group turned out to be pretty decent and we only took down the bosses we needed to so it was pretty quick too. I didn't get any gear, any upgrades I get from here on out will be coming from raid mobs/bosses, but I did get the Chaos Orb at the end so I was happy. I also got my 70 valor points for the day.
At the risk of sounding like a broken record, I strongly believe that a 329 item level is too low for a Tank or Healer to be entering heroics. It is too low for a lot of the dps too in my opinion. The bosses in heroics, as well as the trash mobs, have a lot of health and hit hard. Low dps makes the Healer run out of mana because the fights take too long. An under geared Healer is going to run out of mana anyway because they didn't have enough to begin with and an under geared Tank is not going to be able to stand up to the beating required to tank a heroic. If you get a 5 man group of people in a heroic who all have a 329 item level it's just not going to happen.
Buying gear with justice points combined with 333 item level drops from normal dungeons and rep gear can get you an item level of at least 340, why not wait?
