No offense ment,but What's so great about this,I thought hit area was a bad thing?
To be honest, this weapon or many weapons with Hit Area can be pretty useful, not just in PvM, but PvP-You just need to know when/where to use it. Obviously, being red means you're targeting everything in range and definitely can hurt you more than benefit when in a spawn area type PvP fight. But, group PvP in chokes or open field where people are grouped up trying to sync up on someone? You're disrupting the hell out of them and messing with the dexers as well, as they should be auto targeting you.
Best tip I could give about hit spell weapons is to make sure your primary target is on last target and you spam attack last on them to assure you're hitting them when multiple targets are around.
