I haven't had a chance to play these yet. I look forward to them tonight.
But I think it's worth noting that making good maps is hard. Like, really, REALLY hard. Factors such as sight lines, spawn locations, base designs, landmark placement, weapon placement and balance and more are very hard to juggle, and require tons of testing to get right. And even after putting in tons of work, lots of people will hate the end result.
I put two months of work and testing into the map I submitted to the Forgetacular contest, and was very methodical about it. But even then my map was just okay. When I perused the maps tagged as being for the Forgetacular contest, I found a very poor signal:noise ratio - lots and lots of poorly designed or implimented ideas. I'm sure the designers put a lot of time and effort into them, but that's not guarantee of success.
Also note that the playlist is intended as a testing bed, and the best of the best will bubble upto general matchmaking. This is an approach I was hoping to see. And given that approach, there are going to be good maps and bad maps flow through. Vote accordingly.
I guess what I'm saying is - maybe you shouldn't point all the ire at Bungie, but at the community. Because making good maps is a crazy hard challenge, and they picked from what they had submitted.
