It's true that it is just an annoyance, but honestly it can be a really BIG annoyance.

The biggest problem is having to backtrack to re-establish enmity. Tank's anticipate the mob's route on each pull. They are typically expecting to be the fixed point to which the mobs go on sight. If Regen pulls hate from the start, the mobs don't go straight to the Tank. They go straight to the Healer. Depending on where the Healer is standing, the Tank can miss their AoE enmity grab because the mob ran in a completely different direction than the Tank was expecting them to go. That means you have to go backwards to get hate on targets you should have gotten the first time. It really is inefficient. It's slower. It wastes additional Tp/Mp. It wastes additional Def CD's during the backtrack. It wastes time on offensive buffs that you're not making the best out of. It wastes Dps positionals ... it's just one big waste. What should be a smooth and organized run turns into a functional but vastly less efficient run, especially if the healer is inexperienced.

For experienced healers, its no big deal because they know how to position or work with the Tank, but anyone who has main-ed a Tank has seen a healer who runs away from them when they steal hate. It's awful, and the Tank has to chase them around trying to get it back. I've also seen a healer who griped at me for turning off her pre-pull Regens (which she would re-apply as soon as I dropped them) because I was "wasting her Mp." I would have laughed if it wasn't so awful. Again, not unmanageable, but as far as annoyances go this one can get near the level of Trolling.
