If your opponent fields a 5x3 unit of Orc boys opposite you, why not match it?
10x3 more than doubles your offensive power, while only giving him less thn a third of a boost,
Unit of 30 orca against a 5x4 saurus block
28 attacks, 14 hit 7 wound, 5ish dead saurus,
attacks back,
20 attacks 10 hit 5 dead orcs
Drawn combat
Both as a horde,
40 attacks 20 hits 10 wounds 7ish dead saurus,
Back,
33 attacks, 18 hits, 9 dead orcs,
We win by 2
I'm not saying hordes are always the answer, but you should aim to be matching what your opponent is fielding.
There's no point giving them an extra rank of attacks AND attacks for having a larger flank than us.
You should be looking to maximize attacks, I mean ,,, they are saurus! Unless your looking down the front of a unit of chaos knights, you rant gonna be losing by much, and you will still be steadfast.
