Do you find it hard to tank a party with relics/+1? I do.
For example, I had a party with sch, blm, smn, for AK a couple hours ago, all with relic weapons/+1 while I only had an Ifrit scimitar. It was already pretty shaky before the first boss and by the time we worked our way through gargoyles, it was clear that the blm is hell bent on front loading all his spells on the first target I mark while the smn would throw every single aoe/dot he can on to every mob. I had to choose between barely winning aggro over the main target with focused combo with flash in between and still lose my threat on the other mobs or lose my main target if I push for more spread out enmity to keep up with the smn enmity.
At the second boss we killed the boss before the gnats appeared. The sch mentioned that this is the fastest demon wall kill he's had yet. However, past this point, it's clear the party doesnt care about any form of party anymore. The blm never slept so far so I opted to go for the lights monsters first but my marks were ignored. Blm would target whatever he please and the smn would still go full force on aoe while still attacking my mark. Halfway point I just gave up on running back and forth and refused to chase after things if they peel if off me.
Now, the kicker part. We were at anantoboga and I chose to tank it at corner instead of parallel to the starting position with tail pointing to a wall because other than me, everyone is ranged. Soon enough, my health started going past half health even after I used mitigations and I started looking at the healer sch. He was casting ruin over and over (I'm guessing due to being hyped over that demon wall speed kill). At this point anantaboga started casting catastrophe, I got some reprieve..right? Wrong. I get no heals and I immediately died seconds after he finished casting. The sch raised me but at this point I was fed up. I just ran around avoiding things and letting them deal with anantaboga until we wiped.
At this point they started insulting me and how I did so far through out the dungeon. I finally talked and mentioned what killed me but they denied it and blamed me for eating catastrophe (I was already at 1000/5200 when he was casting and i was already behind the pillar due to corner). It wasnt catastrophe that killed me. The summoner started saying his titan could tank better than me. So I said go ahead and do that. They closed the boss room as I was walking towards it and fought without me. Long while later they wiped. I asked them if they still wanted to do that again and they were adamant. This time I was infront of the boss room and saw how the battle went on. "Watch how I position this titan you bad tank". And then they proceeded to put titan where I was.
The titan still died and they still had to dance around with anantaboga with 20% hp left but they won. Total time so far was 55 mins taken and they felt like they won over me and one of them mentioned that they will tell others.
Rant over I guess.
