yeah. i have been refreshing around 10seconds remaining just to be safe. switch over when around 10seconds is left, and this allows any room for error, or the need to dodge, or a thundercloud, or sometimes to refresh DoT before the Enochian.
so far i have gotten BLM to lv60 and am currently working on BRD. i hope getting some of the other jobs to lv60 will be much better. so far i really don't like the new BLM and BRD :( i don't like seeing the new play-styles and wish they would have just built upon the already existing play styles. leave the new play-styles to new classes/jobs is what i say. :D
ANYHOW, thank you very much everyone. thank you for your advice. i am sure it will be helpful ^_^
