Aloha,
I would like to address a few things here.
Unfortunately with the ships dropping into battles with the numbers at tier IV to say VI the number of CV's in que means that you will get more often than not, more than 1 CV. Though I cannot comment on changes that have not been announced yet I will say this is being looked at currently.
At this time lower tier battles can be challenging to get through as the learning curve is quite steep. But you are taking the first correct step, which is asking other players for advice and how they play. Try to, as difficult as I know it is, to ignore the trolling and nonconstructive responses to your questions. And I hope you do not feel deterred from asking questions!
Mahalo,
