Viks are probably the 'lamest' civ. If you get stuck as Viks on a land map your pretty much screwed, because their bonuses are all either water or infantry based, and it's awfully difficult to raid someone effectively with infantry..........
Well, if you have Viks you have to end the game as fast as possible, and keep it in Feudal or Castle.
If you go imp, it's pretty safe to say that you have a disadvantage and will most likely lose.
I do not find ANY civs lame.
All civs are meant to be played a certain way - maximizing civ bonuses and minimizing weaknesses.
As for 30 BT? If he had the eco to do that, he most propably should have won the game a long time back.
PS. Place 8 trebs with cavarch+rams, keep spamming rams if u want. Even that can be beaten. Anything can be beaten. ...... 'xcept maybe 200 eles 11
