Thank you for the help

Okay, so my army would be something like this.
Warband I
Gulavhar
18 Wild Wargs
326
Warband II
The Tainted
2 Wild Wargs
134
Warband III
Castellan of Dol Guldur with Morgul Blade
70
Warband IV
Castellan of Dol Guldur with Morgul Blade
70
Should be exactly 600 Points, if I am not wrong. I don't get an army bonus, but with the models I have it shouldn't matter to much.
A lot of Wargs, which are really fast. A big monster and 3 more or less good heroes.
Also do you think someone will have a problem with that I am using Fenris wolves as wargs?
What do you think of my warband?
