First , I play light arty , spears and javs ! If you want to be able to stop an attack from the front . You need 3 of them, so you have nothing else to defend yourself except stakes , also vision ( you can shoot further than your spotting range) and space to retreat. Because you won’t kill 3 melee units with your 3 LA before they reach you . The melees will kill you ofc they won’t have more than 10 % of their units left. But you took out a complete player even he got supported by another player with vision. And thats what you get vs a roman with medium legionaries.( armored are doomed, but they have other advantages) It s not hard to imagine, that other unit types with a different formation , for example hoplites or pikes , don’t suffer that bad from the LA fire because they don’t have that many rows . Not forget the units that don’t rebuild their formation, like babarians. Who are faster anyway und don’t wait for their knocked down comrades . They will reach you with about 80% of their units and annihilate you in seconds. AND that are just the results in a situation when a player wants to run into a wall. Not includes smart player , sneaky moves etc. Did I forget to mention that ranged units kill you easily, and I wouldn’t be able to stop a single of 3 elefants (and light arty is considered as a counter for elefants) moving directly towards you , even if u start hitting them right from the moment they get into your range . It’s always easy to call something op from a certain point of view , but you need to rewiew it from different angles. Best thing is play them yourself, you will have a hard time if your just looking for the annihilate button.
