some must really be products of a sadistic mind. Or just something drawn out of a hat. I've played 10+cpc's in a few days trying to get some 'while opponent captures your cp' achievements for killshot & guardian, but haven't improved my count at all. The only option feels to be to hope for a suitable field and stay stalking.
I actually got interested in achievements when I run out of battle point multipliers. In addition, amateur crates are great for some playoffs (as well as skins). And credits are always nice extra. But yeah, A-coins are the most important goal.
Seems like current tournament area is great for beam/assist achievements, and I've gotten some Zephyr pulse cannon kills with AC10 + Pulse 6, just stop scorching with AC before the target dies
