The WaW room is almost competely useless to a CV except for 2 things. 

If you are a BW it will be great.  Gotta love the game promoting BWs, when so many hate the BW and agree that the CV experience is not fair to begin with.

You can truly bank a lot of creds as a FW.  However, I'd gladly trade making 500k in creds a game for the massive experience the BBs are able to get.  Not to mention you spend the entire game getting yelled at for vision while you are target number one for the BWs.

W@W rooms are nice.

In a CV though, it is 95% pointless to go in there as a FW.

As a FW, you can shoot down 20k worth of planes, get 200k credits and only  8k exp.

As a BW CV you can go in there, get 150k atk and get like 100k exp and 250k Credits.

Also, it is almost pointless to atk subs.

Get 50k atk on a SS4/5 = 5k exp

Get 50k atk on a BB5 = 40k exp.

WTF.... fix the reward for killing subs.

so it seems that people like the WaW rooms - but ppl dont play them because of the following reasons

1. You cannot leech, ie no shared xp, you earn what you work for individually

2 If you a bb player who has little skill u become food

3 Xp for cvs is stuffed atm ie only BW do well

4 Xp for subs is stuffed atm ie bb shooting at them is pointless

5 The rooms crash alot
