@CAGOA34Digi has a limited range, besides the fact that you can't equip it on anything other than a P2020 / Mozambique in the first round. Also, death recap was showing a high amount of headshots each time. Many times they were shooting my cover, although I wasn't moving or trying to peak.
As for DDoS, the idea is to not crash the server, because that would end the match for everyone. Instability helps, it masks stronger aimbots and speedhacking and makes it hard to track targets or to push the enemy as the movement is all over the place due to prediction errors. Also, pretty sure it wasn't a typical network problem, as there was a pattern. For about 6 times in row, lag and high ping started right after that enemy Bangalore got downed and ,each time one of us got killed during that instability, it was very quickly, lin one short burst.
I've had tough matches in Arenas and they were very different. You don't get to unload a full devotion mag into the back of a skilled player.
