Warframe

Huge Warframe player here, and I've actually suffered through countless hours of enjoyable grind because of my inability to pick my favorites, aha. I just have all versions and use all frames. When you get to late-game, and have basically all the necessary mods & items, you can have a blast with every frame given you have the right build.
I was messing around with Inaros, and maxed his range, energy and efficiency to become a 100+ CCer with the tornado. Hilarious stuff :p
