You do realize a snide remark doesn't refute an arguement? Also, the one 18 I do have is due to the +2 bonus humans receive to any stat of their choice, and two stats were increased by +1 at 4th level, so the initial spread looked like:
Str 16(+2 for human) Dex 10 Con 12 Int 10 Wis 13(+1 at 4th) Cha 15(+1 at 4th)
I put the 18 into Strength because we don't have another defender/fighter in the group, but even with a 16, it wouldn't have been any problem. Also, because we began play with 4 players, the DM allowed 25 point buy, but if you total up my beginning stats cost, they total 23 points (the other 2 points went towards getting a trained cross-class skill- a DM houserule). Not that much above the 22 suggested in the book.
I also listed the stats so you'd see my defenses were not suffering at all, and are in fact the overall highest in the group. My power attack bonuses are not "gimped" either, and while the damage output isn't huge, its not supposed to be either- thats the job of the ranger and rogue in the group.
Wisdom is not a main stat for the paladin- Str and Cha are. Wisdom is nice to have since it gives you more uses per day of Lay on Hands, but thats pretty much it. In fact, NONE of the paladin powers are based on Wisdom. So again, your arguement doesn't hold water, and several posters have shown exactly why, AND provided the stats to prove it.
Have you actually played a paladin in 4th edition, or are you just going off a read-through of the rules? As has been said ad nauseum, 4e plays a LOT different than it reads. You do seem pretty aggressive in your dislike of the paladin- any reason for this?
