no, team play IS NOT covering for each others failures to ensure a win - team play IS not failing your team in order to secure a win - is it OK to cover for each others failures to ensure a win? of course, just like charity is OK but you dont expect nor require charity, either...
shizato u dont even have a healer at this level. id suggest u actually play it before making any further comments on the matter. and seriously, being heals, ur job is pretty much to cover other people's asses. party comp is different based on their gear. some are easier to heal than others. and most of the time, out of really good premade parties ur gonna be covering for a few of mistakes made by ur party members. DF anyone?
You know, it's not just the getting hit by a plume that can get you killed. Or it's not just DPS. Sometime you, yourself, the healer get hit by a plume. Or the tank lost hate for a second and the mob oneshotted the poor BLM. Or the tank didn't grab the mob in time during T4 and it oneshotted someone. Oh and, you know Swiftcast is not used only for raise, right? SCHs use it to re-cast the fairy or switch it, WHM can swiftcast Medica II in situation like Ifrit Nails, after Ifrit astral flow or Titan jumps.
