Jungle build

When jungle I start with Hunters Call, but you can also start with Hungering Strike, there isn't much difference.

You simply want to max skills in this order.

Flash

- I'd say the best choice for initiate/escape with ww.
- With ghost you will lose the chance to surprise, and when escaping you will have bonus speed from E most of the time anyway, so you don't need ghost.

Smite

- Quite obvious for a jungler, ww can jungle without it but it's most usefulness comes when dealing with dragon/baron.

Ignite

- Some extra damage for you, you can replace this skill with whatever suits you more or your team needs.

Some possible replacements:

Exhaust - You will want at least one exhaust in your team for some fed tryndameres.
Teleport - Can be good for gangs (teleporting to wards), or for not losing exp/gold.
Ghost - If you prefer this skill over flash and whatnot.
Cleanse
Surge - Could work, haven't tried it out yet.

Some impossible replacements:

Promote
Revive

start at blue buff golem with pull from mid, smite last, then go wolves, wraiths, lizard, two golems, back or gang or continue jungling and whatnot
