Why are the slingers in EB so good? I'm wondering if they were historically that good, especially against heavily armoured units with decent sized shields? I would think intuitively that small and heavy rocks would have high lethality but low penetration against decent armour. However as it stands right now, they can badly maul even heavily armoured units. Since EB 0.81, it seems that hey have gotten even more strong(I'm not sure if its the unit size or something else). I can't get normal missile units in range before they start getting shredded by small rocks. I've almost given up on anything without long range for my missile units.

They've become the bane of my EB game and its at the point where I automatically focus all my missiles on those slingers before they start whittling down my elite units. Even from the front, I've seen them able to inflict 10% casualities on heavy infantry before they are able to close. When I use them, I have destroy whole units of heavy phalanxes by flanking them and killing 5+ per volley. They have the ammo to do it and its really mind boggling to me. I never had this problem before...

Were they really THIS good at THAT kind of range?
