a- u could do all of that, or u can go to ww kill banished efreeti(level 65) he doesnt summon, is rootable, snareable and can be soloed by a 65 druid. he has a one hour spawn time and drops banished efreeti heart. turn it into the drake right next to pofire entrance and u get ur srt flag- no other flags needed just potranq access.
also the entrance to Sol Ro Tower is in the 5 stones... think it is the middle but dont hold me to that.
You forgot about getting the BoT flag to and killing Agnarr the storm lord in BoT for another important flag. Also don't forget to get the preflags before killing mobs like Grummus and if you do anything out of order, you will have to see the Seer Mal Nai'She, and say something like Unlock memories to get your flags working.
