gr8stalinI'm not sure you understand the concepts of aiming and reserve ammunition.
Demo spawns with 20 pipes and 32 stickies. More health pickups may help his survivability but he's useless after about a minute of life when all his ammo runs out. If you had to die or run back to spawn that often it'd be a bigger detriment than anything.
MunchOK well here's a better question. How do either of these unlocks positively affect the game and why should we use them if they were allowed? And don't say "to shake up the metagame" or "to make watching 6s more interesting." I want REAL reasons.
You don't ban a weapon because it doesn't have anything positive to contribute, you ban a weapon because it contributes negatively. Maybe some demo decides to actually run Persian Persuader and just plays really aggressive, jumping in picking up health everywhere, but also dies a lot. Unless the time comes when that is proven to be overpowered and makes the game worse, I don't see a reason to ban it.
