It seems that there may be a consensus conclusion around the need to monitor some combination of DPS, EHP (non-dodge) and sustain due to the ongoing presence of RD elite & champion packs. There are also references made to some bugs being addressed by dev team about re: pet damage, minions and RD/Health Link combination. For more detailed information, check out the thread below.
Most of us have been talking about maintaining something as close to 700 AR / 5K Armor as best we can, and keeping HP above 35K. At least, that's how I've considered my gearing approach. But I'm beginning to wonder about gearing with DPS : EHP ratio in mind, especially with the presence of RD elite / champion packs.
I used to think that a 1:4 ratio of DPS:EHP was good, but I'm finding that it's typically not good enough in mid-to-higher MPs with RD monsters since most of the damage I incur is self-inflicted. At this point, I'm wanting to spend most of my upgrades on increasing EHP rather than DPS. I see the place of having sustain, but finding that the mechanics of sustain (that you are incurring damage first before you try to recover from it) as being slightly problematic as you deal higher damage, and for that higher damage to get reflected back on us (and with low mitigation, it takes much more sustain to recover).
So recently, I'm arriving at the conclusion that a ratio closer to 1:5 is much more comfortable, since my DPS can often be buffed to 220K through an array of skills and buffs (not including MoC/Overawe). I'm not quite there yet but I'm finding the closer I get, the more comfortable the fights seem to be (and I don't necessarily need more than one LS weapon).
Just wondering if others out there gear with a specific DPS:EHP ratio in mind. I'm personally leaning towards wanting to keep a 1:5 ratio going at all times. Which means that I'd want my EHP to get closer to 600K before I consider attempts at upgrading my DPS to somewhere closer to 120K.
Or taking it one step further, using fights against Azmodan to measure our "true" DPS and using that as a gauge to figure out our optimal EHP. Anyway, wondering what some of the others thought about this kind of upgrading / gearing approach.
