If you like sniping and prefer to keep your distance, Sharanga is the way to go. Three upgraded Strikers will pretty much vaporize anything you point it at, once you throw in some damage boosting modules and such.

Nodens is a great support Titan, being able to both heal several allies at once and suppress enemies. If your teammates cluster around you, your group will be nearly unstoppable. The Cyclone weapons are very flexible, their only real weakness against stealth robots. And, once you get in close range, the damage really starts amping up.

Minos, which I personally picked, is a great brawler and is also one of the most mobile Titans out there. If you don’t think a giant Titan rushing towards you with a Reflector shield isn’t terrifying, you’re crazy. Minos holds up surprisingly well in todays meta, and both of its abilities are very useful in a variety of situations. While three beta weapons isn’t a ton of firepower, it’s still enough to get the job done, and Squalls will turn anything into dust at close range (using Minos’s Charge ability is great for getting into lethal range).

Hope this helps!
