I enjoy the stats on the Sickle greatly but the Hammer... Not so much and the Sickle could use some SLIGHT tweaks.

1: Make the Hammer stun opponents for 5 seconds IF you get a mini or full crit and reduce the damage and swing speed by 23%.
2: Increase the bleeding time on the Sickle to 10 seconds, that's all.
Bonus: Add an "URA!" bar that can be filled up by doing 300 damage, once the "URA!" bar is filled a special ability can be activated by pressing the Mouse 3. When the "URA!" ability is activated Heavy will scream "UUUUURAAAAAAAAA!!!". After that Heavy can only move forward (Pressing S, A and D won't work). For him and any teammates within the range of 10FT will get a massive 75% speed boost while becoming more vulnerable to all damage types by 40% and their ammo capacity will decrease by 50%.
-That's all, let me know what YOU think about it and if you have better stat ideas.
