Help with some 3.5 crossovers to PF

[gr8artist]

So, Pathfinder is supposed to be backwards compatible with 3.5.
But, we keep finding a lot of 3.5 material that doesn't translate over, because of the way PF redid certain abilities. So, I was wondering if anyone already had a helpful guide on translating stuff over. If not, I elect we start one. Some things I've been wanting to work on, that I'd appreciate input with...

1.Snowflake Wardance (http://dndtools.eu/feats/frostburn--68/snowflake-wardance--2671/) - Since PF changed bardic music to rounds instead of uses, what should the bard expend to use his Snowflake Wardance benefit? I'm thinking 4 rounds, or 1 round of BM for every round spend using SfW.

2. Frenzied Berserker (http://therafimrpg.wikidot.com/frenzied-berserker) - PF changed the mechanics for rage, making it rounds instead of uses. They also changed cleave and power attack. This class would need almost a complete overhaul.
Improved PA - While in a frenzy and using PA, deal and extra +1 dam per -1 penalty normally imposed by the Power Attack feat (so 2/1 lt, 3/1 1h, 4/1 2h)
Supreme PA - While in a frenzy and using PA, deal an extra +1 dam per -1 penalty normally imposed by the power attack feat (so total 3/1 lt, 4/1 for 1h, and 5/1 for 2h weapons)
These changes would give a 20th level Barb/FB a PA modifier of -6/+30 damage with a 2-handed weapon.
Frenzy - Rounds = 4+con+2/level. FB would always need a Will Save to stop a frenzy.
Supreme Cleave - Should be ok, since it isn't dependent on how the Cleave attacks are made.

Feel free to make additional requests, suggestions, etc. Try to keep the number system, like in the Simple Q&A.

There's already a barbarian archetype (http://www.d20pfsrd.com/classes/core-classes/barbarian/archetypes/paizo---barbarian-archetypes/wild-rager) which functionally mimics the Frenzied Berserker.

The archtype is in no way mechanically similar to Frenzied Berserker besides the "hurt your friends and make everyone hate you"

3. Prestige class skill ranks... Obviously this needs some attention, as PF redid the skill rank system. The easiest solution is to reduce the number of ranks needed by 3 (since in D&D, 8 ranks meant 5th level, but in pathfinder it's 5 at 5th).
but I'm not sure what to do about class features that reference "Concentration" checks. That skill got dumped and made into a caster level check for PF. Tentatively, we're using a "Constitution + Class Level" check instead, but I'm not sure if that's a good solution.

Thoughts, opinions, concerns?
Any other ideas of stuff that needs to be reworked before carrying over?

1.Snowflake Wardance (http://dndtools.eu/feats/frostburn--68/snowflake-wardance--2671/) - Since PF changed bardic music to rounds instead of uses, what should the bard expend to use his Snowflake Wardance benefit? I'm thinking 4 rounds, or 1 round of BM for every round spend using SfW.


3.5 Bard gains one new use of bardic music per day.
PF Bard gains two new rounds of bardic performance per day.
If we assume these two measurements are roughly equal, then any ability or feat which specifies that you must spend a daily use of bardic music should probably instead use two rounds of bardic performance.

Ah, yes, and Snowflake Wardance specifies that the dance continues for, "a number of rounds equal to your ranks in Perform (dance)." Due to the changes in the skill system from 3.5 to PF, it would seem to be sensible to change it to "a number of rounds equal to your ranks in Perform (Dance) plus three." Or perhaps plus your charisma bonus.

Has anybody seen or done a remake of the Warshaper PrC?
Also, anybody have an idea on a good limit for the number of natural attacks it can have at once, or how long they last?
