Titan- heart marking issue for melees

[Onyxys]

Target the heart and lock it.
Go as close as the lock allows you to go: you'll always be at the right range to melee it (and yes camera will be messy).
Basically, the target lock prevents you from being too close to melee it.

Aha ha) To lock heart on Titan.ex, where you need always run run run? Funny, thank you
