pretty much the title, i just don´t see people use them in 1v1s .. maybe in a teammatch but even there it´s rare ..
judging by the unitlist assuming it´s up to date with FAF´s latest liveversion

aeonsniper has to compete with the t3 mobile artillery that while having a lower RoF and smallest AoE of the MAs does more damage even if with damage over time, not to mention unlike other MAs it´s capable of firing on the move and has longer range
vs bricks and percivals you need 8 to oneshot 1 of each vs harbs and phim t3 tanks you need 4 and 5 respectively
compared to that the Aoen T3 MA even with the small AoE is still capable to damage more units per shot depending on how clumped up they are .. to which it would theoretically require 6 shots for percies and bricks to die quick enough and 5 for a phim t3 tank, 3 for harbs ..
the sniper obviously requires mobile shields to survive which in case of Aeon seem to be the cheapest in maintainace or otherwise need harbs as meat shields ... if units get in range of it however unprotected .. it´s ded ..
phim sniper is more or less the same except that phim have access to a larger and sturdier msg and you need only 4 sniperbots to oneshot bricks and percies and 3 for harbs and phim t3 tanks ... also compared to the Aoen t3 MA the the phimvariant does half the damage but for a larger AoE but the high damage of the phim sniper could make it be favorable to use
still both sniperbots have the problem that terrain, even just small hills can block their shots ..
spearhead ... yea ... problem with it is that a cybran player easily can send its missiles back with loyalists ...
against aeon it has "only" stationary tmd to fair which like loyalists send the missiles back to their origin ...
now while other tmd "merely" can decrease or maybe even nullify the damage of the spearhead it seems able to take out a fully upgreaded mexx in 3 salvos .... .... it´s also pretty damn cheap for a t3 unit and take 7 to 10 salvos to take out a t3 stationary shield ..
it also seems to have the furthest non T3 MA weaponrange ..
so yea ... how would you use them ... if at all ....
