On my website you will find Troop Spoilers, this is automatically pulled data from GoW to show you what might be coming. There is close to 50 troops, some with all the information you could want others with just a hint. Every time we get a GoW update this page will automatically show troop changes and graphics. The Chest page will show you the odds of getting a particular troop you want and the history of the chest over time. This can be useful to find out when a troop came out or more importantly before you spend keys making sure a troop you want is in the chest. Finally, the Guild Ranking History for the top 50 guilds. This will update multiple times a day so you can watch to see how your guild is doing all week long.
I really hope you enjoy these GoW utilities.
