Man, it's kind of disheartening in XIV to solo POTD or HoH for me. I don't want to learn the hard to do technique/exploit to spin monsters and stop their AI. Mainly because it's an exploit.
But that means that it's more difficult.
MCH, RDM, and any of the tanks have a pretty good go of it.
I've been to the 180 boss on MCH and DRK, and back in Stormblood I got to 176 on RDM. I just can't seem to not flub the 180 boss. I get so close that it hurts.
On MCH I had it lusted, had my STR and STL pomanders on. It was at 17% going into Ecliptic Meteor, and I fumbled it by being ever so slightly too close and got auto attacked on the meteor impact and died. I had a raising and more STR/STL but I was out of Lust, so when I got it back down, I tried to creep with auto attacks to lure it lower. It started casting Ecliptic Meteor at 15% this time, and I got it to 6% before the second meteor came crashing down. Ugh. *Super Smash Bros. Announcer* Failure.
On DRK I did everything right, but I remembered that the auto attack would kill me, so I disengaged, but DRK's DPS is so much lower than a DPS's that they can't afford to do that. On review, if I had stayed in melee range, I would have survived the auto attack, and then I could have used Living Dead to live through the second meteor as I had anyway. The life remaining on the 180 boss was 0.4% Failure.
In Heaven on High(HoH) I only really try it on GNB. I've been to floor 92, where I died. The next time I tried I got to floor 94 and I ran out of time, because I had no more pomanders to speed it up. Gunbreaker is alarmingly good, so durable with so many cooldowns and just enough healing that it can 1v1 some of the mobs that guides say are rated, "Impossible" for soloing.
The only thing I can think being more disheartening is that I saw a screenshot from a Japanese player's Astrologian attempt at solo POTD to 200. Astrologian is the worst job to take, because its DPS is so absurdly low that you start running out of time without a lot of good luck in the 150s. They got to floor 200, but within sight of their crest item, the time on the clock ran out. I've also heard of people getting to 200, and then disconnecting before getting their item. As *** as that is, that's still the whole dungeon.
Since the new relics are linked to POTD or Delubnum Reginae for the final step that's currently out, I reckon I'll try a time or two more for POTD. MCH was very very fast and interesting. DRK is slower but safer. I could take GNB, PLD, or RDM too, and I might. They don't really have much advantage over the other two though, other than PLD and GNB being able to use Landmine traps to score quicker clears if invuln is available.
I hope I make it to 200 one of these days, but I'd even just settle for actually beating the 180 boss solo. Been to 200 plenty with Drac, Ina, and others. Still need to convince Kali to go again sometime. *sigh*
