TORParse is by far the best parser out there for SWTOR. I highly recommend it to anyone who wants detailed, easy to read, and accurate information to help improve yourself and your guild/Ops group.
Torparse is very detailed, you get a tab for damage done, taken, heals and threat I just love it. It's really useful to analyse what happened in a fight.
For each tab one get on top of the classical recap tab and graph,the log of the section you'r consulting, for instance the log of the damage received, which is very convinient to check what killedyou or why as a tank you where taking such a beating.
My only grip would be with the group feature, going back and forth between different "analityca views" of the members is not as easy as I would like.
