tried several open world builds from this
https://metabattle.com/wiki/Ranger my gear is not great, its a mix of yellows and exotic, not fully optimized, cause I don't have the gold to get optimized and I don't have expansion pets yet, only base game ones. I ONLY solo, no pvp, no fractals etc. the mission that basically made me rage quit was night of fires. getting through trash packs was annoying enough but then... boss showed up. he summons way too much trash faster then I can deal with so i can't even chip away at the health at this point, i just keep getting overwhelmed by reinforcements. judging by the fact that I was able to find multiple threads by multiple people having issues with that very same boss (and previous mission where you have to blow up the cannons, for much the same reason of being overwhelmed by too many mobs) - I'm not the only one who had issues. apparently even chat within the game was understanding with those particular problems.
multiple packs of trash with mobs that cc me AND mobs that stop dropping AoE at the same pace as she can move (and i can NOT rolly polly in GW2 the way I can in ESO - seems like 2 rolls in a row, maybe and you are done, have to recharge.) = dead ranger. because if that AoE hits me for more then one tick - between it and attacking mobs? I'm done for. meanwhile boss keeps summoning even MORE trash. at one point I died as soon as I respawned at the checkpoint because there were so many of them, they literally spawn camped me.
I should not have to be optimized to the gills to be able to do INSTANCED STORY missions (yeah yeah, I don't need ascended gear, but have you seen prices for optimized exotics?) and that there is so much disparity between class capabilities when it comes to soloing is bad design. IMO. the fact that game expects me to min max both my class AND my gear to do STORY, makes it not for me.
