New buffs to stumble, ADS, and reload OP
+50% Weakspot from hyper focused, +10% from Jim's passive, + 5/10/15% from Tunnel vision ADS over 2.25s for a total of +75% weakspot damage after 2.25 of ADS
+25% damage from stacked passive, +10% from Silver Bullets, +7.5% from Large Caliber Rounds, +10/20/30% damage over 2.25 seconds of ADS from Patient Hunter, for a total of 72.5% extra damage (When fully stacked and with 2.25 of ADS)
+5% Bullet Stumble and +1 Bullet Stumble from Combat Training, +7.5% Bullet Stumble from Large Caliber Rounds, +10% from Silver Bullets for a total of +22.5% Bullet Stumble and +1 Bullet Stumble
+25% Aim speed from passive, +80% Aim speed from Steady Aim, +50% Aim speed from Tunnel Vision, +25% Aim speed from Cold Brew Coffee for a total of +180% Aim speed
+30% Reload speed from Widemouth Magwell, +15% Reload Speed from Coldbrew Coffee, +20% Reload speed from Reload Drills (Most likely won't be able to pick this card up due to it showing up last, and the last 20% being quite redundant despite increasing barrette/phoenix fire rate) for a total of +65% Reload speed
+75% Weapon swap speed from Cocky, +25% from Cold Brew Coffee for a total of +100% Weapon Swap Speed
Utilities include:
Ammo stash to have infinite ammo secondary (preferably auto glock or tac 9) to help with common clearing, with +100% Weapon swap speed; +45% (or 65% in the end) Reload speed; +200% Bullet penetration from Large Caliber Rounds; and +15% Ranged falloff from Silver Bullets, this will allow you to horde clear very effectively while still being able to swap to your sniper rifle almost instantly
Weapon Scavenger is a must to find barrette/phoenix - aim for having it by the third or fourth map of whichever act you're playing so you can start finding better quality than white
Run like hell +12% Movement Speed and Mad Dash +20% Sprint Speed will still allow you to reposition and kite quickly - however you will be in a bad spot if you run out of Stamina
The ONLY thing I would love to add is Marked for Death +10% Team damage, but hopefully you have a shotgun build support with MFD + Shredder + Combat Training who will also be helping stumbling while adding +25% Team damage (Which will increase your damage by 25% also - allowing the two of you to delete mutations before they get close enough to damage the team)
