[Update 7 - "stormbringer"]

Some of the people replying to this topic that are just complaining or talking about other games needs to take a step back and look at what you're dealing with here. This game is in beta. There's going to be resets, game rebalancing, features taken out and put in like crazy. You're not here to just play the game and have fun; you're here to experience the changes, make constructive feedback, report bugs and glitches, and help the developers make the game as polished as they can for the full release. You should not complain about resets or massive updates during beta, as they're going to happen (one just did!) while the game settles down and becomes more fleshed out for a final release. Complaining about a reset to a massive game feature such as mods or complaining that a new warframe or weapon sucks without providing any details doesn't help anyone.

Play the game. Get new mods. Try out the new mods, and get a feel for the changes. Then, make feedback and bug reports for anything you feel is making the game not play well, and make feedback and bug reports for things you feel are too powerful that trivialize parts of the game. Heck, even providing feedback that says "This feels good" is great for any developer or designer working on any game; it means they did something right, and if someone agrees with you, even better.
