I haven't played ww in some time now. What would you recommend to boost as?

sword of the divine seems promising.

Well i must agree with you, as your reply explains alot to me at least.

1st of all, you are very aggresive, that explains why you are that focused on keeping your "bloodseeker" (i think you ment Bloodthirster? right?) bonuses.

I must admit that ww is not the best farmer so stacking it again might be tricky on late game and dangerous since you stay on lanes or in jungle for a long time.

Also the defensive item sutes you better since you initiate 90% of the fights.

I dont like the approach such as: "I've yet to find anything except doctor mundo to be a difficulty to kill within a few seconds"

This shows you focus on thinking 1v1 too much.

Other thing that i noticed now is your low AS. you only have 40% from items.
Your base AS would be 1.207 without HC. On lvl 18 with maxed HC it will reach 1.719 only. Something you might be interested in is getting some as at least to reach 2.0 with HC.

I edited a few things.

I went with merc treds instead of beserk greaves. You can make up for the attack speed loss by putting points into hunters call over blood scent. I've found that it is a crucial to have the reduced slows and stuns to be effective in pvp.

As far as the last item you get, it is completely decided by your opponents. Lots of aoe, get a leviathan, targeted spells - banshee's charm, heavy armor-black cleaver, lots of cheat death tricks-warmogs

I've also been playing around with exhaust over smite. It feels slightly slow going jungling at the beginning but pays off in a big way late game.

Now, at DEWO's comment. First of all you neglect to consider that you have to be killed twice every 5 minutes with my setup (and keeping your bloodseeker bonus instead of losing it is huge btw). Second, I've yet to find anything except doctor mundo to be a difficulty to kill within a few seconds (dr. mundo still escapes even with your setup). Excessive dps but no survivability gets you killed right quick. (You are not able to go invisible, teleport or flash away (except with the summoner skill) or have any other reliable survivability mechanic except life gain. That being said you cannot play a ww with no defensive stats in higher lvls of play.

Now my play style. It is true that I like to brawl any chance I get. I'm in on the opening kill about 80% of the time. But the trick is to fit a gank into your jungling schedule.

When I play with smite, I kill the 4 wraths on my side of the field at lvl 1 and jump into the middle lane for 2 mob kills at which point I'm lvl 2. At 2 I kill the golem get the mana buff and then clear the jungle on both sides of the map (being aware of enemy positions and hps as I go) When I clear the jungle the first time I am about lvl 8 and have enough for the b.f. sword. I shop and then get both buffs and kill the dragon. Then run the jungle a second time ganking at opportunity. At the second jungle run finish, the team fights begin and then its a team game.

When I play exhaust I play a lane until lvl 3 then do about the same thing explained about.

I've had success doing both strategies, its a gamble really. The exhaust way you need to pick up an extra kill or two to make up for the slower jungling. The smite way you handicap yourself late game when the skill no longer is useful.

A playstyle desc would be nice :)

@Items
I will agree this is a bit diferent but i dont know why you get BT as 1st item if your playstyle is Jungle/Gank.
You start ok with long sword so i would see the razors at least coming right away.
Instead i see a BT witch will take you VERY long time to complete while you jungle.
Jungling is not the most effective way of getting gold.

On late game you focus on defense. Well... its nice that you dont die, or is harder to kill but:
BT+Bloodrazor as only damaging items make you a rather an annoying fly than a damage dealer. So i dont get it "It also makes your character considerably more powerful than DEWO's late game." Where?
It makes you way more survivable than mine ofc. But as you started in jungle, and focus on late game it will for sure take you ages before you get cash to get your core. Becouse you wont kill much early game as i recon.

Total item cost = 13655 gold. (5 items)
mine = 13135 (5 items)

Your AD/AS = 245/1.367
Mine AD/AS = 320/1.623

Your Def (Ar,Mr,Hp) = 172/68/3412
Mine Def (Ar,Mr,Hp) = 104/60/2192

Considering that i take Mallet as last item as a (survival+Utility) i get that nessesary HP boost still remaining extremaly dangerous.

You might focus a bit more on a "fighter" type of playing, while i jump out when i see enemies at 50% or already used their main cc abilities already. Or when i need to do my job (Ulti on nunu/katarina and so on)
You might go straingt into a fight after the tank.

Well Build is ok, lacks description for sure, and sutes a more aggresive playstyle.

whether I go to blood scent or hunters call first depends on my opponents. I often will put more points into blood scent if the opposing team has characters which can rapidly flee or are very fragile. On the other hand, hunters call is very handy against sturdy characters who will want to go toe to toe with you.
