Alright, this is actually worth explaining so I'll do it.
#1 The Fate of Konor pits the Imperium as a whole against Chaos, i.e. all Imperium players (which make up the vast majority of all 40k players) against all chaos players (which make up a small minority of all 40k players) and then based the campaign off of the number of wins and losses. Not to mention any faction infighting counted as a victory for that faction just to make it worth playing for stores that are completely overrun with Imperium players (which are most stores). So the stage was set with the Imperium on the top of a very steep hill that chaos players had little hope of climbing. As if that weren't bad enough, the extra points were given to people who decided to buy and paint new kits for the campaign. And guess what the only new releases were for the entire 6-week period of the campaign? Yeah...
#2. Releases aside, Space Marine players got their codex at the start of the campaign, while chaos players got their halfway in. Remember that analogy I made earlier about the hill? Well imagine if the Imperium player was given a bucket of caltrops to pour down the hill as the chaos player was climbing it, with the new rules, the new units, new stratagems, etc. and the chaos player was told "Don't worry, we'll give you some gloves in 3 weeks."
Meanwhile the Chaos Space Marines codex left out the two most played subfactions of chaos these days, the Death Guard and Thousand Sons. Don't get me wrong, I think it's good that they have their own codexes, but that's still just arming like half of the already small playerbase. So... instead of gloves, maybe just... one single glove.
