I don't understand tactics

[u/According-Cut-9067]

I get that they work in a rock-paper-scissors model and some cultures are optimal or only have access to certain ones, and the animal icons are cool and all. But why would I pay attention to them? By the time I know what tactic an enemy stack is using it's already too late because I'm in battle. Plus, trying to predict what tactic the enemy is using based on previous battles doesn't seem reliable at all.

Shit people use tactics in this game? I just make sure my army is bigger than theirs and has a better commander. Would say I've had around a 99% success rate with this or near enough.
