Shovel owns, huge distance and a lot better than axe. In GM u own everyone.
In GM it's different , But because Shovel have huge distance , it take them longer to strike again , there weakness is when they strike , it will take them around 3-4 sec to strike again and 1-2 sec to hit. Axe can counter the shovel by getting into the shovel second's delay. Instead of axe using Right Click , Pro axer use left click on the mouse because it like the regular knife right click. Left click for axe is fast and only 1-2 second delay to strike again. Regular Knife take 2-3 second to strike again. So Axe have a huge advantage if used right.
Shoveler is Great for killing noobs , but once a left click axer come you will be in trouble. It will take around 7 round to understand the Axer strategy and weak point. But for pro or noobs left clicker shoveler can detect the axer strategy very easy. Shovel has also one great thing is the Shovel Jump tech, it when you jump and use the shovel to kill , this is very effective and can surprise a lot of player.
