All the while I wasn't making new entries I was still playing FFXI. I find it hard to think of everything I've done in that time as it's not like I write stuff down, take regular screenshots or parse everything. Also, I may be getting old, because my memory is failing me. Since there have been no more LS events in such a long time I've spent time doing stuff on my own or with very small groups. Revisiting old NM's we had done in larger groups and dispatching them with ease prompts me to ask "How was this stuff ever hard?".
Eccentric Eve wasn't hard when we did it as a group. However, people did fail to Stun the breaths at one point. Loads of people hit the floor because of charm and EBB. Getting pops while farming for Dark Rings (still yet to see 6% anything) is a natural side-effect so it's a very acessible NM. It turned out to be a simple duo NIN+RDM. Relying on Violent Flourish is kinda wonky. Subbing BLM on RDM removes status cures form the arsenal which can be a hassle for the tank, but /DNC will take care of that eventually.
Kukulkan was a bit tougher. The terror gaze attack REALLY slows down what is otherwise a very simple fight. The unremovable poison is painful, but at 90 NIN evades most of it and RDM can cure through it. There are some trees that make it really easy to kite if you have to. I believe we duo'd it 4 times. The last one I nuked through the gazes to speed up the fight. Knowing how to kite around the trees means you can go all out.
Isgebind seemed really rough when we first fought it. While getting hearts for Masamune we trio'd it twice, once using the "healer outside of party" trick (avoiding Spike Flail) and tanking it on its tail.
There's loads of stuff like Ironclad Smiter (3 ppl), Ansherekh (solo), Titlauacan (trio/duo), Lusca (duo), Amhuluk (duo) and many more that really seem easy the 'second' time around. However, the biggest difference in difficulty for me personally was doing Glavoid recently. It's clear now that with a tank a healer and a stunner you can trio it very reliably. Each time you fight something you can learn from it to get better at it, but it feels like you learn MUCH faster when you're either soloing or low-manning things. Probably because it's less chaotic and/or you're more focussed. It's fun to see things get easier as you figure them out. Too bad we have to do a ton more of them for empyreans and it gets less fun each time. However, for me there's still a bunch of things left to try.
