You don't need either of them really. They are adventure packs. The first one bloodline is like $5 and the Splitpaw is $8. If you have the All access deal you automatically have access to both of them. Neither is a must have IMO, but to each their own I suppose. Splitpaw is mostly instanced zones for people lvl 20+ while the bloodline is more in the 35ish range. I played my first charactor to 50 without a single invite to a group in either of these zones, and I am working on my 2nd at lvl 27 and have yet been asked to attend a group in either of these zones.
