so assuming you had 10 racial ap to spend, it would seem that human definitely stops being the best choice for a ranger.
the question then is, is horc or wf overall better? horc i think translates more easily from human and gains plenty of benefit from those 10 ap essentially for free and without any real need to spend more than that. wf though could possibly pull 6 ap from somewhere and get 15 additional mp. the problem with wf though i feel is that 6 ap is kind of pricey on a ranger but could be mitigated by not spending on survivalist since it wouldnt give prr in mithril body (according to the wiki anyway), but you are also down 2 feats compared to a human, and are paying a hamp penalty.
anyway. thoughts?
