Getting the sword ultimate (2500 upgrade) makes most of the chiefs a joke. You can just spam 5 combat executes on him in the middle of 10 orcs to kill him. It´s kinda cheap but they don´t play fair either.
LOL. Yeah, there's that (I actually did that on a mission where you were not supposed to take damage when killing a specific Warchief), but the meter for that takes a while to build up. It's also one of the upgrades that someone should get a lot later on. That and the stealth kill equivalent are definitely the better two of the three bottom upgrades. The bow version not so much.
YMMV but put the runes that give +% damage at mid hot streak levels and at high hot streak levels in your sword, and also use one that returns life for a flurry or head explosion kill. Then there are also those that have a chance to return all of your health at a specific hot streak number.
