One of the things that I really like about the Kings of War rules set is the versatility that the game (currently) allows when it comes to figures and basing.
I have not played WFB for a very long time, I think 2007 may have been the last throw of the dice for the game at that time. Though I did start to play 3rd Edition WFB with a friend, but he's wandered off to Warmachine/Hordes and I've found Kings of War.
Below are my miniatures which I have re-based or used as is for the troop types in this game.
The Treekind became Forest Shamblers and the Treemen Tree Herders. No issues with basing here at all.
The Wood Elf Glade Riders made he easy transition to Silverbreeze Cavalry.
Dragon Kindred Lord and the Wood Elf Warhawks I am currently using to represent Drakon Riders.
Missing, but seen in the group shot are the Elvish archers. Mixture of Wood and High Elves.
So there you have, my entire collection of WFB Elves have merged across into Kings of War with very little qualm. There is about 5,500 points of Kings of War units, more than enough to allow some leeway in troop selection for 2000 point games. Now to get some more games under my belt.
