5 down, 3 to go.
Yes, the remaining 3 spots are going to be the most difficult to decide.
Dave - I was looking over your PC and we have a lot of similarities, I was going to select the Summoning Staff as well, grabbing very similar feats (Staff Expertise, Hafted Defense, and Improved Defenses) to you also...
Yeah, artificers have been hosed since their introduction...one of the forgotten classes of 4e (along with Runepriests, Str-Clerics, Seekers, and Assassins).
The staff as weapon/implement is the same for the Sentinel too...at least the increased reach will let me hide behind my bear protector (who has lower defenses and hp than my PC)
