I'd say this answers the questions.
General remarks:
Rabies dmg is calculated over the present weapon slot (recalced every ±0.2 secs if I'm correct). This implies that you can hit with a fast weap then hit W for your facet swap (6 sox weap 3 sox shield is +45% dmg and - 45% res).
Second: Rabies KILLS. Unlike for instance plague javalin, rabies doesn't leave you at 1 hp, it kills. There is one ground rule though. If a char goes out of your namelock range (2-2.5 screens) rabies will leave the target at 1 hp. So if someone knows this (very few do actually, so sssst!) keep close enough to watch them die.
Third: Oak. Don't bother using it. You'll have low mana, no fcr and you'll be chasing 100% of the time. Recasting oak every 10 secs will break your chase and only leave you vulnerable. Just build it without oak
Gear:
Weap:max ias bp is reached with 105 ias in a War scythe. Optimal sock I'd say would be 3 sheal 3 15 ias/15 all res. Great vs casters and alike
For a 1 handed weap, you would need 100 ias in a war axe (range 3, best speed). I could be wrong here, but afaik there is no frame difference in 100 ias or 120 ias. So 5 sheals / 20 life jewel would be perfect there.
Armor: shaft is the way to go in most duels, but having a 20/-20 armor is absolutely useful where dr isn't needed. Socket the shaft with something without stats (pruby for example), else you won't be able to swap.
Shield: defl mod 3 sox (atod most likely, adod if you can get your hands on one) for 15/-15 socketing. Any other shield that you prefer for normal blocking. Could be whits, but since you'll need to have mb with the ATOD, any shield with lower dex requirements for MB will do. I use a sanctuary dragon shield, which provides a lot of useful adds which whits will not give you.
Belt: I use a 24 fhr/15str/60 life belt, for the simple reason that 20 fhr is a bp for ww dru. Without fhr you won't hit even with 4 fps. Could chose to not use the str, so you could use mavinas/string in some setups which is obviously very valuable.
Rings: Ravens. Get swaps like dwarfs and sojs. For instance vs necs sojs> raven.
Helm: pure melee fights for example barbs/drus/smiters; perf jalals pruby. In all other setups: 3 shape/ 30 frw/ 2 sox. Again, prubies I'd say.
Amu: 3/100 in melee duels, 1 dru / x frw/ xx life/ xx res for all other duels. I might actually have a 1 dru 6 frw 6x life for trade if I'm correct.
Boots: aldurs, no questions, gloves: TO, pretty obvious.
Inventory:
10 skillers, a mix of 30 life/ 7 frw would be perfect. Depends on your opponent. I also have some 12 fhr's in stash for vs for instance windies where fhr can be very useful (might have some 30 lifers for trade as well, just pm if you need them). 10 times 5 frw with res to fill it up.
Setups:
Keep in mind the first remark: dmg is recalculated. So when facing a sorc for example dont waste a slot with Oath for fury which will never hit (oath SC gives a 7 fps first hit which is useless vs many chars). Pick the range 5 war scythe, 4 fps hit them, swap to full facets and watch them die.
Make the right evaluation for how much frw you'll need et cetera (on mine it varies from 100 to 150). Oath fury can be very useful vs druids, barbs, pals, java's et cetera. You'll hit around 1-2.5 k fury with a 34x% ed oath so don't OVERRATE it. Rabies will be your killer, fury has but one skill in it.
My druids stats with similar setups:
2.7-3.3 K life
Rabies dmg varies from 20-50 K
Frw 100-150%
Fury dmg: 1k-2.5K
Stack resi etcetera always possible with armors/charms/sockets et cetera.
