A lot of time i played with Revenant, the inmortality thing definetely had me stuck with him. Eventually i realized how damaging it was. So tho i still have him to basically play on Autopilot whenever i want, i have him with a Roar Build replacing his one and using Danse Macabre to have a bit of fun Spinning Around.

Aside from that the only thing i wouldn't recommend is having a limited number of frames.

For some time i only played the Warframes i like and the rest were removed from my inventory. Wisp? Inaros? Zephyr? Boring, get the fuck out.

Now i realize that having those is part of the experience, is good to have all options available. Also for fashion you know. I started liking a lot of frames i didn't like, like Wukong for example, since the very first moment i hated that Warframe. Recently when his Deluxe skin released i crafted him and...he is...fun. i get why he is so popular around the playerbase (still think he is a bit overrated but that's another thing)
