I'm one of those players that plays less characters than I'm entitled to, but I think I will try a character in WI to see what that island is all about. 
It's not a bad thing. All I'm saying is that if someone tells themselves they only have time for two characters, and they are attracted by the WI, this extra character slot may not translate in an additional character.
About the War Islands, I'd also add something else... BM is not the same as it was back when we last had them. If we expect the same results, we are bound to be disappointed. The War Islands relied heavily on a team spirit that has long since vanished. Might yield good results, but it might also end up being as war-like as FEI is an "RP island" and Dwi is an "SMA island"... not at all how they started out and what was hoped of them.
