On the contrary; the combo jumping can be used in conjunction with this.
Someone else mentioned how you still end up staying in one place over the duration of the rest of the combo...
However, most people are using really fast animations take bear shaman the combo is finished as you hit the ground for theirs same with barb mostly tbh (I play a barb and still think it's ridiculous)
The barb in particular though in a single sprint jump lands a long way away when he has arcane marauder or haste up... further if both xD
Combo jumping also increases the distance your combos go green at *YES I HAVE TESTED*
If you are chasing someone you will go red if you don't combo jump the combo, if you do combo jump it somehow reaches them.
It shouldn't, but it does. That's a straight up advantage. I should know, I use it on speed hackers and comber users that sprinting during combos xD
