Going to echo some comments above for emphasis. This announcement leaves me with more questions than answers.
1) What was the deciding factor in moving the $1 tier to $3? The feedback from the community was consistent and negative about that decision. If the answer is, "We still make more money losing 600 people" that's cool . . . It'd just be nice to have some acknowledgment. Asking for feedback and disagreeing is totally in your purview (obviously) but from a customer service or communication sense, not showing you heard or understood those concerns is worse than not asking.
2) Statements without a plan are pretty meaningless. So saying "increased dedication to producing behind the scenes content" means . . . What?
3) What will content be going forward? Just CoS and Nebula Jazz?
I was looking forward to this announcement because I thought it would offer something better to supporters. For a second the battle maps bundled with the ezine sounded awesome--but the sample map was so plain/uninspiring that it undercut my interest in shelling out more money to see the other maps.
So I guess my point is: my take away from this post is
A) some higher tiers have been lowered, but are still huge investments.
B) Battle maps (based on 1 example) are not worth paying for (and the ezine is a fan mag, which is fine but not something I personally find interesting)
C) Low tier costs more money without justification
D) No concrete plans for how things will be improved
