Lunge doesn't jump on friendly targets consistently

So I made a support class ( Paladin ) to play as aura bot with a friend. The issue is that you need somehow to be able to keep up with a full movement speed rogue so the way I wanted to do it is by using Lunge spell and To your Aid talent to be able to blink on your allies. But this doesnt work 80% of the time. It’s really necessary to have a skill to follow up your team m8 as a support and taking that away makes the game a lot unplayable. Can you please fix that ?
