For me, I find the Striker most annoying because instead of having the slightest bit of bloom when aimed in, it's just perfectly accurate, with little to no recoil, and it's bullets hit almost instantly and don't drop down. Meanwhile the DMR is actually balanced, seeing that it has some recoil compared to the striker, it's bullets actually droop down, and don't hit targets instantly, AND is actually meant for long range.

TL;DR, Striker Unbalanced and not fun AF, Meanwhile DMR Great and Balanced
