This is mainly for DTV mode but could be used on battle too.
So.....
Tired of 'teamates' wearing crappy armor and using minimal weapons because they are cheap bastards who love losing much more than winning? Do you care more about your team winning than making/saving gold? How about a new feature called 'war chest'? How it could work is on your web character page you can buy whatever items you desire and put them in this chest. In game it appears to all other teamates as 'free' gear they can equip (note each item you buy only counts as 1 in game item so if you want to provide more buy more). You (the buyer of whatever gear someone uses) pay the upkeep on it.
