Standard 4 tile converter.

+Preemptive conversion is vital

-Awful chain combo

-Effects outside of conversion are extremely niche

Pact is a testament to how in demand preemptive conversion is. She has the worst chain combo type in the game, an irrelevant equipment, and her only saving grace is that she applies Slow, which usually doesn't come up (and is even difficult to apply since it's through her awful Chain combo!). Despite all these flaws, she's still incredibly important, as having any sort of preemptive conversion is necessary to get teams to function on most maps.

Note: Most of the Preemptive 2-CD converters should be viewed as a staple for the purpose of the early- and mid-game, while endgame content favors multiple teams. Other converters often require BTs to get Pre-emptive and/or an acceptable CD.
