Leaping shot op in Online mode?

So i am playing in offline mode for some time i nearly finished everything and i am currently sitting at level 23. I must say i found some pretty op combinations related to ranged class. With leaping shot - skill which makes you jump backwards and shoot multiple projectiles + passive skill that lowers cooldown on each crit + very highly crit based equipment i managed to solo (Like with 1 character) strongest of 10 dragons under 30 seconds.

Now i know it may be normal for level that high but i fought the first dragon for like 5-10 minutes and thought it was an epic battle. Spamming leaping shot 15 times in 30 seconds(since no cooldown and leaping shot is really cheap on energy) and killing dragon this way really does seem op to me.

The leaping shot really is a nuke with this build. My question is, how does this look in the multiplayer version? Also im currently playing at default (second) difficulty.
