Staff is the one to watch out for. With Staff Expertise and Staff Fighting, you're looking at a Defensive 1d8 Two-Handed Simple Weapon with a Reach of 2.
I considered this but I felt that there is too little benefit from it to justify the expenditure of extra feats. Defensive is overshadowed by the Battle Lore's +2 AC bonus, the staff isn't versatile so the damage is lower than mace/spear/morningstar, clerics don't use staves as implements, and the reach simply isn't needed with, again, the Battle Lore feature.
Nice as a flavour option but for optimising, it's fairly weak.
An eladrin with Eladrin Soldier and Spear Expertise and Feycharger cheese, however... yeah, that's actually getting into the silly range. The +1 to hit on those powers is going to make all the difference and, in all honesty, I can see being errated down the track because of charop builds making it way too powerful.
