I'm a Hunter main, but decided a little while back to start building up my Warlock and Titan so I could go raiding with them. I started out grinding on the Warlock. I had fully unlocked every tree of the Light subclasses long ago and wasted no time in retrieving Stasis. I never got the achievement for unlocking all Warlock subclasses, and still haven't for no apparent reason. The Titan playstyle had never really appealed to me before but I buckled down and put in some work anyway, enjoying it more little by little as I went. Thing is, though, I hadn't really actually PLAYED a Titan before. And by that I mean I didn't even finish the basic tutorial missions before they swapped it back over to the Cosmodrome, so I had to start that whole thing over. However, as soon as I was able to start messing with my subclasses, I received the achievement for getting all of them for the Titan. I haven't even gotten Stasis yet, so I can only assume that bit doesn't count. Anyone know why this might be happening? I really don't wanna have to delete and remake my Warlock just to re-unlock everything in hopes that THAT'S the problem...
