Some fights are easy, some are hard. But the key to all are the mechanics. Take Sins in Shavarath. Gobs of mobs to slay but the end fight my be short and simple (dependent on choice of course). In others like invasion (Shavarath again) the trip there is long, random but not ‘too hard’ but the end fight can be grueling if you don’t have a divine that can drop blade barrier and run in circle while healing and remove curses. 2 quests out of the same area with entirely different difficulties in the end battles.
Some end battles are no more than ‘beat the bag of HP’ and others are contingent on constant maneuvering. Example – MoD – constant maneuvering while going in, beat some HP, then move out when the mark of death lands on the boss. It’s chaotic and messy.
Shroud end fight; surround the boss, beat a bag of HP and get constant heals. Done.
ToEEs end fight is a mix of MoD style ‘stuff is about to go nova’ and ‘surround and beat it’. But in a small confined area which makes maneuvering pointless (she’ll hit you with the spell spam and you’ll end up spending more time healing a low MRR class than anything else).
To that end, the end fight is boring. You either go in with a good PRR, MRR and heal amp toon and just stand there and smack it – hide by the sheltering shroom when the waves of death starts and beat up creatures when they spawn, then go back, drop a consecrated ground and continue beat up mommy fungi demon.
Or you run hysterically in circles trying to avoid spam of spells and self heal a lot, getting knocked down a lot and waste a lot of resources.
The tragedy of the end fight is simply one of class choice; either you have the one that can take the beating and stand there and smack.
Or you don’t and it’ll be a more miserable experience.
Ideally you’re with friends. Maybe 2 massive dps self heal barbs and one pally dropping consecrated ground and then a divine spot healing and a caster throwing out tons of dps. In that case the end fight will most likely be a breeze. But soloing you should stick with DPS, PRR/MRR and self healing, heal amp. I like my Vanguard but I assume my Pally will do just as nicely. The arty was a mess and my sorc was a dread. I wouldn’t bother with my ranger because of the low MRR.
