The reason of using strelet is to overwhelm your rival in early game, don expect to win in equals battlets after a 15/20m++ game if ur rival did well.
But they could receive some upgrades to don’t be so useless in lategame as u say, I don’t disagree in that. More range sounds fair to me, +2 range in veteran & maybe +2 in industrial, is kind of sad that one can’t use such a funny unit after industrial age cuz is just not worth.
