Why was it implemented that way? Was that intentional to let all characters use grenades? Cause i think when you are bad at throwing every miss should throw the grenade right in your face.
Probably because there are several types of utilities in the game that anyone can use - bear traps, caltrops, and nades (not even counting the electronic utilities... although the taser requires electronics i guess). Honestly, if you think about how powerful psi is just by itself, it's really good that non-psi characters actually have a couple of tools in the trunk to help them out with cc, aoe, etc.
And yea, I have to disagree. Anyone with an arm - EVEN A CHILD - could underhand toss a grenade like 20 feet, not even to mention dropping it at their feet.
I'd prefer if we minimized suggestions that nerfed non-psi characters as well as being completely unrealistic.
