[@UnusualStranger] I see. I personally do not find having 2 of each grenade is too much, mostly because the materials and time needed to make more make production of more very difficult after those are spent. Yet, if you insist, I shall only have 1 of each.
Now, I took the idea for the SCAR from my characters backstory, where he used a similar device to examine the Elemental flux of the SCAR. The chip might seen overpowered, but you should note that it is not, in fact, a real tracking chip; it merely Fires bursts of the kind of power that the SCAR detects. It is basically the magical version of having a thermal tracker and sticking something that keeps itself hot all the time on your target.
And don't worry, I will scale back my equipment as much as is required for gameplay balance.
