its simple really, everything up to HM titan is Pug/gear open a lot of these ppl fate grinded to 50 with very little core knowledge of their job or ppl have been carried to HM titan. I do think they should consider grinding a day or two on CM and AK to at least acquire a few choice DL gear and accessories just to be better prepared and even a few HM ifrit and garuda runs for weapon drops will help tremendously but getting on them for not isn't your place, join a FC and work together with ppl that are well geared for the fight.

its a PUG, you get what you get!
