I'll keep it short: Forerunner and the Battler are such addictive weapons to use in the Crucible. As a lifelong PlayStation gamer, I never really had the opportunity to play Halo. Part of why I originally fell in love with Destiny PvP was due to its relative resemblances to Halo for obvious reasons.
The Halo-style hip-fire on these guns are so, so great, and I really hope Bungie considers making this more commonplace going forward. While these may not be meta weapons, I still want to use them just because I get to hip-fire. They're that fun and that good!
