Volcanic Heart is a bad map

[Corbeau]

If you are in melee and someone ducks around a corner, you can move a similar distance they did to follow them and re-establish LoS. If you are at range, you have to cross the entire ranged distance in order to re-establish line of sight. Which is why the long lanes on VH don't matter: they're perforated on every side, which means you absolutely must close anyway because nobody is staying within those long lines.

This is much less of a problem if you're a non-Bard ranged class, but Bard specifically relies heavily on their filler and their filler takes a stiff damage penalty for being up close. It's also less of a problem if you're a burst class that can dump and not care that someone dodged around a corner - but Bard specifically favors sustained damage, not burst.

Part of why I picked up a melee class in pvp is specifically so I could feel reasonable queuing for pvp when VH is up. Map feels great on melee!
