Dodge or Shield Ram?

Before I start, I'll just say this isn't anything big, so don't expect to be blown away.

Sometimes when a horde of enemies swarms you, it can be extremely difficult to do anything against them. So adding a dodge mechanic might help with that. Maybe bound to V by default? There would be a cooldown between dodges, and after each consecutive dodge, the cooldown would get longer.

If you don't really want to add a dodge, that's fine. Another mechanic to look at could be a shield ram, an attack that would either knock enemies back a few blocks or stun them, so you have a chance to tackle the swarm in smaller chunks. Again, there would be a cooldown, same as the dodge. But instead of a specific key to press, you could left click (attack) while holding right click (block), and you would dash forward a block and slam into enemies in your path
