under normal circumstances TP should never be an issue.

abnormal circumstances are like speed runs. or tank-n-spank action on easier dungeons. in which case you can use your own TP to gauge the TP of others. during a speed run just hit up the TP song when you are half empty. for tank-n-spank runs through low level dungeons, the only person that should run in to TP issues is the tank. but they will stop to restore it. you can play a song to help speed this along.


under normal circumstances no player should have an issue with TP. though sometimes a WAR may need to use Overpower more often because of a powerful BLM. so if you see them using it like 5 or more times. then you could sing for about 10 seconds.


only other time TP would be an issue is if someone died. they obviously going to need a boost. about 15 seconds of singing is good enough. and really even then you won't always need to sing. if they have Invigorate it will restore TP for them. also, again under normal circumstances, if someone needs TP chances are they are going to use Invigorate first anyhow. but tanks can't use Invigorate.


all-in-all TP is almost never an issue. yes it would be nice to see the TP meter of other players. but not important.
