Interesting developments! There has been work by @real_tabasco_sauce to give melee units more combat value which would go a long way to make sniping a secondary form of micro, with actual movement, formations, and positioning being more important. Sniping, automatic or not, is not a great place for the game to be.
During fall of 2021, the meta was all about melee units (mainly pikemen) allowing ranged units to be invincible. Around that time I learned how to snipe using option/alt after watching berhudar spread women out on his berries and since then I have been teaching players to snipe who are frustrated/want to learn how. I figured if everyone knew about it it would be fair, but its just not good to have such a powerful micro technique not be obvious to newer players, 0ad in multiplayer right now is basically divided by those who snipe and those who don't. I suppose we just have to all vote for @real_tabasco_sauce's melee rework when its on the ballot
