I get where you're coming from but for most players, the usual 4 crutch perks are needed in many serious runs of zombies. Similar to what you said in your closing statement that not picking up the crutch perks made you play in new ways you never played, it's exactly like the way I play BO4 and why I enjoy that perk system so much because when integrating the perks into the gameplay it allowed me to play in ways I never would have. The systems that substituted the crutch perks were not perfect but the variety felt in the different playstyles was really enjoyable for me. I respect your opinion though, thank you for the video and have a nice day.
I feel like you begin to learn that you don't need the original four when you play maps with perks that have overall greater benefits than just reloading faster or doubling your fire rate. PHD and Stamin-Up come to mind.
Interesting you didn't do IW/WWII. Similarly to Exo Zombies they don't have the traditional perks but they still have equivalents like the armor in WWII. I just feel like if Exo Zombies was "close enough" they would've been too.
For me I think Black Ops 3 Zombies had a good system for justifying different perk choices due to the changes to the core gameplay mechanics and systems.
I actually did this in black ops 3! I got to round 30 on the giant and just quit simply because I was bored. The only perk I got was the hidden staminup, because I don’t like having a 3-gun carousel in case I needed to swap to an emergency weapon.
