I'm an obsessive completionist... Taris drove me nuts 'cause they wait until you're running back into the hangar building thinking you're gonna get to see a new planet and they're like "oh hey, here's another bajillion missions on the other side of the map!" and I sorta just fell to my knees and screamed in horror...
But I managed to get off Taris last night, so now I'm free... until I go back and level my other 3 alts... >_>
I usually am too, but I just don't want to severely outlevel the content... if I did all the bonuses I'd be like 8 levels above what I should be... lol
I guess this way too (not doing them), I have more to do the next time around with another character. I just hope I'm not missing anything substantial
