Like more than a year ago, my static was WHM WAR and me BLM, it eventually gained a NIN and a THF, up to 62 we'd usually got a BRD or a RDM in the PT, but at 63/63 we got a static RNG, we leveled up to 73 with that setup, with that setup, we would always get constant chain 5s one after another, and no refreshment of any sort, not even juices, not even V cloak and I hate black cloak (only use it for farming or coffer keys or w/e when I don't get a chance to rest), it IS possible, but like Skaw said, people have drilled intheir heads you can't PT w/o a RDM or a BRD, the truth is, people wanna see 200s on the "you gained XXX exp points" message, my static would level in the most weird places, we'd chain VT mobs endlessly and do 5~6k per hr, because we killed so fast, I would only debuff, MB and sit again.
About BLMs overnuking, I have yet to PT with a good, hell, a decent BLM, most of them love to burn their MP, to all BLMs out there TRUST IN YOUR MELEE THEY DO DAMAGE AND THEY DO A LOT OF IT, being in that static thought me many things, I'm not saying that everyone should do that, but just saying how easily people forget that. Good players are able to succeed in bad circunstances.
MNKs, DRGs among other jobs which are extremely underrated, so sad people just wanna do stuff only one way, like the people who shout in Jeuno "Promyvion-whatever need x2 SMN x2 RNG and WAR/NIN" seriously, I've done Promyvions w/o any of those jobs and aced them pretty easily, wish people would open their minds a bit more when it comes to exping.
About that RDM, lmao, I had a good laugh, and I'm sure you were angry as hell, thanks for the holler tho, now I know I won't pick that guy.
