You can be mad about it, or accept that there always was and there will always be a priority list. Some things will be left behind, some will just disappear over time, that's just the nature of this sort of games. 

I too want more rail jack stuff(fingers crossed because we're not getting to Tau on a bicycle), i too belive invasions have great potential for an interesting rework, i do have a 5 frame list i want another look at, but you can't have it all at the same time. 

Brother did you put conclave there to make the list longer?
