Yes, it makes melee boxing much much easier - apart from the fear recovery, it can...

- remove the need to run through mobs in pve with your main to get your followers in range
- allow you to use your main to position a mob before having your followers run in and engage (e.g when you have to face a boss away from the group like the last boss in H-AN).
- allow you to keep in melee range of mobs that move without using follow
- allow you to split your group and melee multiple targets at once

The only drawback is that spamming the Interact with target key can cause strange behaviour on your toons...for me it makes my toons run aound the target (which looks hillarious but isnt that great for dps).
