I would use freeze because you can slow down opponents and run away and can literally bound them and kill them even tough the damage is 10 points lesser than firebird in m3. Firebird is kind of like a ghost or a suicide killer who haunts you even after death! It really depends on the player if you are tactical choose freeze else firebird! Kill each other well Tankers! :)

Freeze

about 40% times when u suddenly get busted up and wonder why, the answer is the shaft owners.
