Okay so this is a question with a story.
So every time I've come back to SWTOR in the past, I usually end up skipping the bonus missions. Didn't seem important, and I just wanted to focus on the story and character customization.
But this time with SWTOR, I told myself I wasn't going to do that. I wanted to make an effort to collect as many codex entries as possible. Get super invested in the lore and stuff.
And part of that involved doing the bonus missions and bonus planet series. I didn't want to take the risk that one of those missions would unlock a codex entry and I'd miss it.
So the goal was to not leave a planet until I unlocked every single codex entry on it (excluding data crons).
...And then I found out a few things.
First, most of the bonus missions didn't unlock Codex entries. I think the only one I can recall that did that was that one entry mission on Republic Taris that gives you Governor Saresh's entry. While the extra exp was nice, it was still a whole lot of running around...
Second, I found out just how damn hard it is to actually collect codex entries. A lot of running around to get into specific areas to get the lore object, a lot of looking at guides because "guide dang it," and finding out just how hard it can be to track a specific creature.
(In case you're wondering how I, a returning player, wasn't aware of the struggle to complete the codex, I had some degree of awareness about it, but I didn't really get how bad it was until Tatooine, where I learned most of the creatures I needed for the bestiary achievement were in empire territory and that would involve a lot of running around with no taxi and/or fast travel to lean on.)
So yeah, I'm really rethinking this "get all bonus missions" goal now. I'm enjoying the extra XP and the lockbox you get when you finish a planet's bonus series, but I'm just not sure about continuing on about it now that the main reason I was going through with it has been stomped.
So, uh...how worth it is it to do all the bonus missions if I'm mostly playing for the main stories and character customization? And if there are a few bonus missions worth doing, what are they?
EDIT: Also I should note by "bonus missions" I mean "exploration" missions as well, not just the bonus planet series if that wasn't clear.
