I was reading in another thread about how you need 30K dps for vet dungeons. How PUG's fail more often from bad DPS than from bad tanking/healing. I had no idea what my DPS actually was, so I added a combat meter and ran some dungeons in my Magicka Templar, Magicka Nightblade and Stam Sorc. I have 370 CP. Before I get into builds and gear, let me say that my single target DPS on bosses from beginning of the fight to the end is about 10-14k on all my characters. Very often it was below 11K. So this is just me "playing" dps without research, just relying on my above ground PvE and public dungeon experience as to what "kills stuff fast". My 3 characters have all cp 160 equipment at least purple and all have gold weapons. I use food/drink, good weapon traits, weapon damage enchants, pick a reasonable Mundus stone, have tried to pick good sets, use potions, self buffs, empower myself, use dots as well as DD, etc.
What I am saying is that I feel I have done a reasonable job at being knowledgeable and prepared for pulling my weight in dungeons.
Yet clearly I don't.
I couldn't for the life of me figure out why my dps is so low. I like to figure out stuff from within the game, but I wasn't making any progress so I started googling DPS, spec, rotations, etc.
I was NOT happy with what I found out. When I read one long post on Magicka Templar DPS I was shocked. I had never heard of "weaving" or "animation cancelling". Most of the morphs that I had picked were the "wrong" versions (Like picking Radient Glory for self heal over Radiant Oppression). Many of the spells I thought were weak were actually strong. I had no CP in Damage over time, yet the advice is to beef that up. Etc, etc. I have Thief Mundus stone, all gold gear, Julianos divines, Arcane Will power, Torugs (head/staff) and Kena shoulders.
So I made some adjustments, relearned some things and tried again. My dps went down. I was so confused with timers and the whole weaving thing. And I can't seem to move around and dodge when I am trying to also do complicated things. I added a buff timer addon with a unique sound per buff. Ding, ding, buzz, rrrr.. it is like an electric rod showing me how non-optimal I am as each buff runs out, usually when I am on the wrong bar. And meanwhile the boss is moving our of my aoe, my "weaving" keeps messing up my casts and I keep switching to the wrong bar at the wrong time. I am now dying a lot more as well.
It turns out that the biggest issue with my DPS is how much I suck. Maybe its my age, but I can't really handle that kind of mental gymnastics and hand eye coordination.
So if this is what we expect our pug DPS to be doing I can see why there might be issues. How many people go an look up stuff and put in the time to get truly optimal? I tried and I still suck. I probably can handle a 1 bar rotation. I am lucky if I can remember to empower my ultimate. If there is lot of ground AOE and I have to move around a lot my DPS goes into the toilet.
Now that I see what is involved at DPS I have to rethink every prejudice I had about roles. I find it much easier to tank and heal. I can even heal, debuff boss and do some dps. But I am sure I will NEVER get a sustained 20K single target dps in any fight where I need to move around.
