if i had my druthers

wotc does not want to alienate gamers by changing existing class builds radically; instead, wotc adds more builds reflecting how they would have done things differently. one downside to this approach is the pressure to continue supporting builds that, in hindsight, really should have been done better, which is a bit like throwing good money at bad money.

here is how i would have made the original builds:

cleric: wis, con or cha
fighter: str, con or dex
paladin: str, cha or wis
ranger: wis, str or dex
rogue: dex, str or cha
warlock: cha, int or con
warlord: str, int or cha
wizard: int, con or dex
