Alright, after thinking it over. Since we're making Deadeye a joke beyond compare now, I'll take a stab shot at silly balance changes also.
1. 3000 range. Same range as a ballista in WvW. Just all the range. Snipers have extreme range and the story mode Deadeye has even more range than that. Perfectly balanced as all things should be.
2. Everything pierces. Every single DE skill that fires a projectile will pierce. Snipers execute priority targets and the biggest problem Deadeyes face right now is when random enemies screw up your rotation when they get in the way.
3. Buffs granted by allies next to your marked target are applied to you also. Simple QoL so we can power trip our sniper fantasies from across the map better.
I invite all other Deadeye players (if any are still left) to pitch in and help "balance" things out.
