I always fill, but I'd rather not when I see a heart pendant nub on either side. Those aren't the kind of people I want to give krogmo coins too. There should be a minimum amount of loadouts, and you should be able to inspect them all completely.
"But I dun want people to know I use HP pendants!"
Then you're a complete [cog] for using them even though you're ashamed. Don't go against your own convictions please.
You get games where neither side uses heart pendants?
Please, tell me where you find these games. I would love to play in them.
Aside from that, you can tell when someone on your team has HP trinks when their loadout is Striker and they have more pips than displayable in the left-most portion of your HUD.
