The problem is that Revan is only really cared about in the foundry FP. Some characters make vague references to Revan, and the only story that I've seen so far that even cares about Revan or someone who has a connection to him is in the JK storyline with Lord Scourge. Not to mention KOTOR2, being made by Obsidian, has VERY vague references made to it. The Exile is very scarcely referenced to by any character. While playing both of them matters to a star wars fan, it doesn't mean **** in this game since it's 300 years afterwards. If it were set 20 years after KOTOR2, then I would agree with OP. With that huge gap of time, it doesn't really help.
Roll a Republic character and go do the Taral 5 and Maelstrom Prison Flashpoints.
Meetra Surik (The Exile) and Revan are covered in those, since that's how The Foundry FP is set up in the first place.
