Sometimes you can invade if you know their jungler cannot dual you without help early game, so I want to ask for a list of junglers that pretty much you should NOT dual early game, if anyone generous enough to spend their time and list every single champion, thank you.
it's relative depending on who you're playing and who the enemy is playing.
- if he lands a Q on you at level 2 you're pretty much dead as any jungler. Very invade happy because all 4 of his skills are an escape of sorts.
- Not very directly strong (as in stupid autoattack slugfests) but he will usually start the fight, and there it is to his advantage due to a few things: him getting the first hit, you taking 0.5 seconds to go "WTF???" before reacting, and he usually takes 
in place of your
. Countered by .
- He's strong. That's all there is to say. If you try him in an autoattack slugfest, he will beat you, and he has the ability to chase down as well. 2 champs who might beat him are 
and 
, but these 2 can't really stick to you like . Perhaps 
post 6.
and - Very strong duelists in slugfests because they will outheal your damage while pumping out their own. But their weaknesses are being kited, since will never catch you once he misses his first axe, and won't get you anymore he blew his ult and fails to kill you within the first few seconds after.
Yet, against each other, it's hard to say because they're all strong duelists. But for weaker junglers such as 
and 
, it's no question, avoidance is the better idea, as well as preparing for a jungle gank.
I'm mostly focusing on pre-6 dueling, so I'm not including ultimates.
is honestly one of the strongest duelists early in the game.
There are some junglers that duel exteemely well like
this doesnt mean that you who are playing for example 
or should not invade
because especialy on there first clear there will be a moment whete they are doing their camp getting to below half or even 10% of their hp right now you can easily kill them and steal theit camp clear some more have a level/gold advantage
and this means the champ you would not be able to duel you can now bully
