ORCS Haven't become more powerful and versatile. Your statement made me laugh. Have you read the new Orc and Goblin army book, or are you just saying that because u got your arse handed to you by a better player?
I play orcs at a tournament level, and what the new book has done to my army is a joke. 75% of the magic items of old are gone, which relates to about 95% of the magic items in a decent tournament list. There magic is now no-where near as good as it was because of this. Goblin wolf chariot became 1 per special choice. Goblin wolf riders points cost increased by 20%. all fast stuff in now proportionally more expensive. Animosity is much worse and if you wanna do something about it you kill your own guys. the magic banners are a joke. There are 2 pieces of magic armour, neither really that good. The magic weapons are meh.
Overall O&G have taken a big big hit and the only way they can feasably be used now is as mob hoard, throwing unit apon unit away at the enemy. How is it more versatile that only 1 army type works now, whilst before there were at least 3.
When i say this bare in mind i'm talking about it tournament play, not down the local GW against someone who thinks taking slann is a good idea. Any army can do ok against muppets who dont know what there doing, im talking about comparing decent lists played by decent opponents
