More so, havoc wrecked havoc on the servers (i know! Ironic!!) due to the fact that there was so much going on. The worst case scenario being that a havoc round caused all servers to shut down. And for serious players, nothing is worse than the server crashing. Not because they don’t want the downtime (trust me, they do), but because they don’t know when it’ll come back on. So now they’re stuck checking into a game for hours because they had armies about to go into a battle and had every intention of turning and now they can’t. Causes a lot of unnecessary stress.
However, I will say, havoc did do a lot of help newer players have fun and learn more game mechanics. On top of this, most serious players will stop playing at havoc (because they spent months not sleeping to get the rank) which means newer players can thrive more.
