has always been a brawler/bruiser. Using nearly any champ in Jungle is possible, what is not possible is the use of 'Devourer' since 6.9 hit, you may be mistaking it for 'Bloodrazor', its successor. Back to the brawler/bruiser part, she is most dangerous when playing that fine line of damage/tankiness, not to be confused with Riots vison of Juggernauts.
While games generally don't last long enough to consider replacing your jungle item after a while, I find it to be a great idea, since eventually you will out-scale the jungle mobs, and focus mainly on helping the team as such there are better choice for that item slot especially since the jungle item mana regen is useless on non mana users, but still takes up item stat points. Further on the topic of itemization, once you get a tanky item or two, damage will need to be focused on, either Hydra will work. If you desire a more health based and regen approach, Titanic, but if you put more value into for AD Ravenous will work just as well, more so if you are able to throw in a BT.
-- Would be ideal at full build for as split tank game, take note that is Cinderhulk not Bloodrazor on Stalkers.
-- Would be a more ideal AD heavy, but the
&
are the two big swapping out items here, depending on what you need, as a more AD heavy team will warrant the need to go more towards:
&
or
or
depending on pref. While a more AP heavy team would need you to go:
&
or
or 
NOTE: These builds are just suggestions to go by, for what one would shoot for if the game allows for a full build, I hope you get the general idea of what I was trying to show.
