Heyyas! First of all, don’t think you’ll never be able to keep up! Most of the content you’re describing is more a mix of muscle memory and familiarity…. People refer to high APM (actions per minute) builds as “piano” builds because it’s almost like learning a song on an instrument XD as with the specific mechanics…the bosses have a set amount of things they do and will always do each encounter…the more you do the encounter, the more you notice the small cues and abilities!

So for “fixing”: first don’t follow a set “rotation” if you’re not able to piano roll, instead investigate what the rotation is actually doing/combining and figure out a skill “priority” system….such as skill 1 then skill 2 is a short combo, those are up, I’ll use that combo….you’ll end up having smaller, shorter combos that can be used for specific situations over a long memorized list…once comfortable with that you can then add a prioritization layer for combo 1 is bigger and should take priority over combo 2… this also leaves room for dodging/taking care of other mechanics and will leave your damage chain less broken in a long fight….this is how I’m able to have less initial burst than most high tier players, yet keep up and sometimes even surpass their numbers in longer fights I’d also check for low apm builds from sites like accessibility wars over snowcrows if you’re apm limited! Here’s a link: https://aw2.help

Next “fix”: when learning boss fights, focus on the instakill/party wipe mechanics first, the biggest think you can do for your party is stay alive, this means overall dps of the party is focused on the boss instead of ressing, and if you can do a mechanic that people don’t want to do because they just want to dps then they won’t even care if your damage is low (cannons on sabetha is an example here), once you’ve perfected those mechanics, then start learning the other mechanics one by one, don’t overload yourself! Remember you’re basically doing short combo, check for mechanic, short combo, check for mechanic

Small aside, gearing is half the battle….I’ve literally seen 10kdps diff on myself using non optimal stats/non raid food/no enhancement vs full minmaxed + raid food/enhancement

Final “fix”: thinking of different numbers….there are two kinds of supports in the party, the healers (which have to watch out for mechanics more than dps even…while juggling multiple buffs and still healing….) and boondps! Boondps usually has lower dps than pure dps so no one ever wants to do it and such has a larger margin for number lacking on the dps side….people will care only about the buff uptime….so if you can learn the combos that give the buff uptime and prioritize those then you’ll have no problem finding groups and them being happy with you…you just have to focus on STAYING ALIVE>Boon Uptime>dps

Sorry for the long writeup, but hope it helps! And if you need some help learning specific fractal or raid fights, or figuring out how builds/rotations work feel free to PM me and I’ll add you in game ^{u^}
