I will add:
- barkskin grants with 5 resist bash slash pierce and -60AC to rangers, though it grants about 30 resists to druids and it's a blocker for them
- flank is almost useless cause everyone can flee without lags and without any efforts
- skin and tailored skin - just useless, newbie stuff is much better
- as for third pet with feat - approximately, you can call it one time per 50 hours with strong restrictions, though it's not so tough and angry like mummy, for example
PS:
1) barkskin was suxxed after some rangers took combos like minotaur+barkskin+bison affinity+solamnic plate or belt of trophies. Those ranger became invulnerable or almost invulnerable to physical attacks. There was found a solution in suxxing of barkskin, though not every ranger had bison affinity. Every ranger has barkskin, but not every ranger has bison affinity, or he is member of solamni or herecy, or he is minotaur.
I would suggest to suxx exactly such combos by dividing solamnic powers, like it's in takhisis. I mean rangers have one type of powers, fighters have another, clerics have third, etc.. The same with herecy.
Bison affinity and minotaur resist were suxxed too, it's right, but not with barkskin...
2) I don't know why flank was suxxed and I think it's not right. I remember two warder rangers with their pets tried to catch my thief with old flank, and I could flee from them, but they had chance. Now they don't have any chance even with more flankers. I've tested flank a lot, and I always could flee from second-third attempt (I remind that these attempts were without lag, in one round).
So I would suggest to improve current flank, it's blocking ability, or return back lag when fail flee attempt.
3) make skin burnproof and resisted from corrosion, at least, and I would like it has some coefficient of compression, for example, if some sword has weight 10 pounds - it will weight 1 or 2 pounds in this sack.
make tailored clothes better than newbie stuff, but worse than elite eq. And add some random affects during creating, like 10 res fire, or -50ac, or 10dr, or 50hp, or... And fore sure with higher skill you have better affects.
4) make this feat valuable. For example, with this feat you can call third animal of worse type at the same time when you use animal call. 'animal lion' - you call two lions and one bear. 'animal bear' - you call two bears and one lion. 'animal falcon' - you call two falcons and one lion. Surely the chance of call third animal depends on the skill of this feat, but it should improve with higher speed.
uff, where's my beer?
