iam surprise to see the gvg every time 50/50 win's.. oops.. i had never seen a gvg that is 38/39 or 42/43 etc.. that clearly state the gvg position in game ..
Im guessing your basing this on your own experience, as its not true

Right now gvg is most rewarding for doing the most possible with the most ease. Few guilds care about their rating and either dont know how, cant afford to, Or simply dont care enough about gvg to properly have all members of a guild in proper sets. The combination of these two facts simply causes lots of farming on the easiest targets they can find, this is why you see the constant 50/50s.
Any set can be beat somewhat easily if its buffed, but GvG as it is now rewards effort though time invested in coverage and watching for income after setting up defenses properly. When two guilds that care about rating enough meat, you will see some truly epic battles many of which dont involve either side getting 50/50 without finding the other with no green lights on.
Unfortunately there are very few guilds that take pride that much in the art of gvg.
Anyways, amongst the top echelons of the ladder, what Graves is saying about cloak is to a certain degree completely viable.
People in this very thread have done 24 hour stands to ensure GvG victories.
Guilty, and I know Im not alone at all in that club (not necessarily within the thread)
If the target is online anyways, there is very little chance of you can hit them safely at all anyways if they know what they are doing. With this buff though being at 2 hoursish with Mrew master, thats a lot of game hours logged in they can skip without having to worry about being online.
I think RJ's solution of simply reducing the duration to 30 mins rather then the 90 it is works great. This would also cause for alot more gold to be sunk to pull off such a tactic as Graves is projecting let alone overall.
What scares me most is that its only "Lesser" cloak
Keep in mind I love the buff though, I think its fun :twisted: Just overpowered in duration :evil:
