Yeah I was hoping with the release of Alacatraz and with the permanent buff of WM to TL 10 (doesn't feel like it though) that Defiance would remove the ability to zerg and make it a meaningful race again. The guide was written before certain advantages were know to exist (i.e. the Zerg and Tanking).
The reason to Zerg is much deeper and harder to change then just trying to win now. Without damage numbers there is nothing to to shoot for. Score maxes out quickly without gaming the scoring system if you are doing straight damage so there is no incentive there either. I mean you get approximately your score right be fore the crystal armor breaks. In some cases its laziness, in others its the mob mentality of well let's get everyone in so they can participate and get a shot of top loot. It's everyone gets a trophy time so let's wait so we can have more people get a participation trophy.
Yes, there is no early guidance in game about how to kill things quickly. Actually there is not a whole lot of guidance at the start of the game period. No mention of EGO levels and how it plays out with you guns and shields. No mention of nanos and their effectiveness and utility in different situations. A little bit of an introduction to stims and spikes but no mention at all about rigs and chips.
It is easy for a new player without access to the knowledge of a veteran or forums (remember the minority of players) to be completely lost.
Thus they enter Expeditions (near end content) get pwn'd and complain or quit.
TLDR: Defiance approach is participation not excellence + No built in guidance for new players = learn as you go inferior builds. As well as sage well written posts and advice get ignored by the majority.
