Interesting...I too really value ASIs and feats. The wait hurts, especially for two attacks. Just out of curiosity...why tome for combat? And why level 9 pal instead of 8?
Yeah on blade. And mostly yeah on gfb and bb. Although taking 3 attack cantrips (EB, Shil, gfb or bb) might be too many, depending on what other cantrips you might have wanted, especially since you do get a second attack from paladin. It's not a bad choice to have though. (Ignoring Shil *and* gfb/bb might be good too.) Or, do take both and if you want more cantrips later, there are ways. The new radiant warlock combines nicely with gfb. Pa11 becomes less interesting, etc. Second attack is generally less interesting for quite a few characters, given gfb and bb. I'm not sure that was a great design decision.You don't need 2 attacks if you take green flame blade or booming blade as one of your cantrips. That scales up no matter what your split. And you really don't get anything out of blade.
