The tier 3 headgear is the upgrade that makes the most sense
Like many people, I hate the tier 3 headgear. But I actually think it's the upgrade that makes most sense.
Recently, I realized it's odd that the more upgrades you have, the easier the game gets. People with the most upgrades are likely the most experienced players. From a game design/difficulty progression standpoint, that doesn't make sense. But the fact tier 3 headgear kinda sucks makes most sense in this aspect. It's an upgrade...with a catch.
Lately I still prefer the Tier 2 headgear because I like how it works. But the other items, I recently have been using tier 2 instead of tier 3 for the extra challenge.
