I disagree, simply because of the lack of people who attend GvG. Maybe instead of enhancing the current items which would make the rich better than they already are, different items could be added to attract people to actually GvG.
Another suggestion: Kind of off-topic but maybe a restricted amount of people per-guild should be allowed into GvG for the time being, this would make the teams more 'even' and encourage more people to go. This could be altered as the population of the server/popularity of GvG goes up. Just an idea, like any idea, it has it's downfalls.
