Some quotes from a previous "Newb War" suggestion thread:
Not every event needs to be a spin-off of War. Why not just a different event, and for newbies only?
no, we already have plenty of event/tournament to cater to newbies
personally i find that all tournaments/events are newbie-friendly with a few exceptions
newbies have the biggest slice of the pie here
whether you'd do well or not in those tournament is another matter
we dont need newbies-only event
It's already difficult enough to find 104 players to compete in War, so it's pretty much going to be nearly impossible to find another 60 people who aren't already involved in War and have them sign up and actually stick around for the 3-4 months that the event will take.
If someone really does want to be accepted into a team for War in the future, they're much better off participating in PvP Events and weekly tournaments, and doing well in them. Even just being able participate in a PvP Event to completion shows to the Masters that a player has the time-management skills to not back out of a high-commitment event like War.
