Got it! after a killing streak, but that wasn't related apparently.
no change in stats, upkeep is the exact same. WHAT DOES IT DO?
also i do tend to wear my default gear pretty much all the time.
EDIT:
[08:30] <@chadz|afk> it's an attempt to go away from the excel-min-maxing, towards a roleplaying game
I think 2 things of this:
1. The bonus is fake, and makes you think you have a bonus.
2. The bonus is real, but it's impossible to find out what the bonus is, thus, you can say you have a bonus, saying you are better in /things/.
Not sure how to explain it, but, it might be or not be the difference between 1 hit less to kill/to get killed.
TL;DR Live with it, and enjoy you have a bonus.
Atleast, that's what i think about that statement.
