They can be handy, depending on who you're facing.
In more friendly games, they can carry a lot of weight.
In more competitive games, they can be a point sink
I've found that at a pretty low T (even s3 wounds on 5s) and low I, they most often don't get to live to use their potential.
Like everything in the beastmen book, they're over-priced. 80 points for core chariots may sound good; but here's what they're missing:
- tusker charge effect
- decent leadership for the ever crucial Primal fury/ tests outside the ldr bubble.
- holding power
- notable saves (4+ becomes 5+ vs most any troops....and so on)
Now, despite all this, they excel at taking out light cav/ skimishers etc etc.
That being said, your Razorgors and ungors can more than handle this.
Beastmen army rely on swinging combats to YOUR advantage. You need to be able to hold up the enemy and keep his elites away from your crucial combats.
what does two chariots get you? 6 wounds, 2d6 impact (IF you get the charge) and really only 2 primal fury ASL s6 attacks.
What does the same points get you in ungors? 30 or so ungors that have a smaller footprint, ranks, primal fury, parry save, command options and more.
Not only that, but the March 10 vs move 7 is HUGE in the army that has to take the fight to the enemy.
If the enemy is sitting and shooting, or has shooting of ANY kind (casket, trebuchet, blow-gun-machineguns, etc etc) the chariot is a free 80 points. I've had games come down to those two chariots that were sniped turn 1. If I'm lucky, turn 2.
Against some enemies, the chariots are better than average; T3 opponents. However, when you're looking for reliability and the ability to hold an opponent, I'd go with ungors any day.
Ungors can recieve and hold a charge from hellpits, chosen and the most elite and nasty due to 'steadfast'. Can chariots say the same?
Will augments help chariots as much as ungors? Wyssans affects ONE unit. (etc etc)
You're right though: Gors won't be winning on their own. They need help. Weather through magic, flanks or chariot charges in the side, they need help. One casting of Wyssans helps them more than a chariot charge would. T5 s4 monsters on the field.
I'm not saying they're total rubbish, but they're not as potent as people think.
