There were times where the only character I cared about enough to log in daily was my war island character. Never a dull moment for me there.
Also, I feel that the WI might help with keeping new players interested, since they wouldn't be bothered by too many off-putting details or general boredom. They just pick a side and jump straight into a perpetual war. If they like this 'simplified' version of the game, they'll be less inclined to drop out of the game because their non-WI realm is boring because of a lack of warfare or active players.
I votes yes.
