New items would really switch up the way the game is played and add a breath of fresh air. Some of these (most of them) are old suggestions, but the main idea is just that getting new stuff to play with would be awesome.
Spear- Heavy item-3 eps/swing, blade skill related, does the same damage range as a machete, however it is armor piercing +2. Meaning that more of the damage it deals gets through the armor than would be usual. For example, you start off by doing 1 damage through the armor. With a spear, you'd do 3 damage through the armor. Instead of 2, you'd do 4. Instead of 3, you'd do 5. Armor breaks at the same rate as normal.
