I use it for PvP in modern Minecraft servers and it has sick COMBOS!
FightBot (3.05 Reach+3.05 to follow+ Auto Speed+ AI Disable)
Criticals (Full Jump)
Now bind all of them on a same key & activate it when necessary.
This is an Awesome combination and is almost unbeatable.
(I use this set-up in Tank, Speed Tank and OP Duels!)
All I have to do is just left-right to make some SICK combos.
I'm hoping to make a video about it soon!
Fun-fact: This does not violate any Vanilla rules & is not detectable.
