Yeah, to be honest, Attack doesn't mean all that much to a Ranger.
Every point in it increases the damage by 1%, so with 10 points in
attack your damage output goes up by 10%, while investing the
same 10 points into Speed would mean something between half or
1 extra action (depends on the enemy Speed) inbetween enemy
moves, so that's a dramatic increase.
Only thing that Attacks is good for is lowering the chance of being
disarmed by the Orcs, but since that only makes you drop the melee
weapon, again - not worth it for a Ranger.
And just like
makiki mentioned, going above 40-50 HP is useless as
well, because the chance that enemies will be able to dish out that
much damage inbetween your moves is pretty much negligible. Not
only does the Ranger move too fast for this to happen, but should
you somehow find yourself surrounded by powerfull creatures, then
there's always Scrolls and Wands of Teleport or Mass Teleport, the
Dog to help you out in melee and if nothing else works, you could
simply Recall.
