Best comparisons I can make for the base ults: Rangers ult is an AoE tracking one that gives you the entirety of the bar to lock onto as many things as possible before launch. I don't know anything that matches up to. Colossus I dont plan on playing it so I have no idea what his ult is but I hear it's a big bomb. Storm closest comparison to the Y1 titan slam but its ult is an offensive support setting up for combos an crits to all enemies it doesn't kill in the AoE. Where the slam is simply a kill move on and doesnt set up for anything PvE wise. Interceptor mainly looks like a blade dancer / nightshade, but all that falls through because its invincible during the period of time making it closer to Valkyr's Ult in Warframe than a Destiny Ult. As for the 5th Javelin none of us know what that holds.
