Battle Stomp is a strong, cheap AoE skill that applies the strongest CC in the game; knockdown. This is the status with the least immune enemies and also benefits from no prerequisite status (wet/chilled for frozen, etc).
Unlike Battering Ram, Battle Stomp has extreme ease of use, not requiring any tricky Line-of-sight or pathing to attack enemies. Stomp can even hit enemies on higher ground. Also unlike Battering Ram, Battle Stomp also deals good damage, the same as a standard melee strike, and is on a lowish 4-turn cooldown.
This is one of the starter Warfare skills, and can also be used effectively by Rogues. It is a strong, very efficient AoE knockdown skill that requires very little thought to use effectively.
It is, in short, overpowered.
Some easy fixes to this, I think, would be making Battle Stomp have friendly fire. This would force players to think a lot harder about positioning and when and when not to use this skill, with the potential risk of hard CC'ing one's allies.
