How are we meant to know we are getting shot? apart from our components being destroyed every 5 seconds. Please let the projectiles be visible at longer ranges.
I honestly think the Colossus needs damage falloff on its Skylance cannon. I don't think it should be able to snipe Bastions out of the air at distances where they won't even render properly. As a tradeoff they could get buffs to their ability to resist air strikes, so they're not super squishy closer to the Bastion.
