Up to act 9 now and Innocence and Brine King are the only bosses to have given me real, tilt level grief. Innocence I was tired and under geared, but it is a long assed fight. BK just has such a small area to work with and my setup prevented me from reliably dealing with the adds.
It’s a shame you can’t ctrl-click the boss entrances, but people would just abuse the shit out of it for running bosses over and over again, so they have to reset the entire zone, really.
PoE doesn’t really slap you that hard with the ‘your gear sucks’ stick, until you hit few of the bosses. Good rolls on a low level item can carry you a long, long way in this game, unlike most other ARPG’s. But sooner or later you will run up against something that will force you to reconsider your gear, and it is usually a boss (or the resistance penalty transition). For me it used to be Brutus (lol), then it was Merveil, then it was Dominus, then it was Malachai. I don’t tend to have problems with any of those now, on account of my growing experience with the game and with knowing how those boss fights play out.
Now when I have pain with Innocence and the Brine King, it is much easier to recognise both gaps in my passive tree and gaps in my gear. But just as importantly, I have not yet learned the mechanics of those fights, so the first few times will be a problem, particularly with unoptimised gear. That just is what it is, when it comes to boss fights in general.
I do appreciate that I can brute force them down, however, as they would otherwise become a barrier to XP progression, what with penalties for being out of level (+4 over area level and penalties apply). If you had to spend a few hours grinding for gear to pass Malachai comfortably, that means you also ground XP and that can have a drastic effect on your XP rate for the remaining 6 acts! There is stacks of content in PoE. There was stacks before Oriath. There is tons of content in progression. There is tons of content in end-game, but I am glad the latter isn’t barred off by hard-stop gear check boss fights in the progression portion of the game.
If you really want the challenge of downing a boss without dying, well the option exists for you to reset the zone.
I have taken to quickly you-tubing upcoming bosses to get the gist of the mechanics before hitting them, which has made my subsequent attempts much less frustrating and much more successful. They are still dangerous and sometimes long fights, but at least I don’t die four times just learning the basics of how they play out.
