Currently for Power Guardian builds its generally Marauder for PvP and Berserker for PvE.
I've recently gotten into a Raid guild, and was immediately told that my Marauder gear was bad and that I should swap to Berserker before I do a proper run of a raid.
And so I did, 70 Gold later, I swapped over my 6 pieces of Marauder's ascended armor to Berserker stats and at first I didn't think too much of the difference, I had gone from 14255 hp to 11645 a meagre difference of 2,610 HP. I Immediately noticed however the frequency of myself going down in Fractals and Dungeons was at least double what it normally was. Such a tiny difference in the HP pool affected my game play significantly. So I began to think mabye I should've stuck with Marauders like I originally had instead of going to Berserkers; This made me decide to look at some numbers. I didn't run a full set of Marauders as there is not enough items to do that. So I decided to compare my old gear vs the new and found some rather interesting results. I'll Include the links to the gear sets I ran so you can see for yourself
Old Set : http://gw2skills.net/editor/?vVAQNAR7/m0ABFChddil4BTuA2/WgWbg8VkqKAslqXA-jxBBQBKU9n8obAAXEgA8EAwy+jSszoEMLKPAA-e
New Set : http://en.gw2skills.net/editor/?vVAQNAR7/m0ABFChddil4BrKAslqXyFw+3C0aDkviUA-jhBBABnpEEr9HlfB8EAA4iAUp6P5pbAA-e
Power - Old = 2804 New = 2867
Critical Chance - Old = 57% New = 56%
Critical Damage - Old = 213% New = 220%
Health - Old = 14255 New = 11645
Marauders = +2,610 Health, + 1% Crit Chance
Berserkers = +63 Power, + 7% Crit Damage
And for some further thoughts I compared what the difference in DPS for the Strike, Vengeful Strike, Wrathful Strike chain for the great sword would be.
Marauder = 967 (2059) -> 967 (2059) ->1450 (3088) = Adds up to 3384 - 7206 Damage Total
Berserker = 988 (2173) -> 988 (2173) ->1482 (3260) = Adds up to 3458 - 7606 Damage Total
So the difference between the two in this DPS test is 74 - 400 Damage on the greatswords basic attack chain
All in all I'm perplexed, The extra DPS small and the Extra HP although not a large difference made a significant impact on my survivability in PvE content. Has anyone else had this issue? What seems more worth it? The Damage or Survivability?
