Hundreds to thousands of hours of grinding to get all the stuff you want, or just pay real money to get it right away.
The grind for this game has always been bad, but it's only gotten worse over the years.
There are bugs that existed when the game first released that are still unfixed.
Duviri was quite possibly the most bug-filled update I have ever seen for this game. They even gave you the option to leave the missions early and keep most of your stuff because it bugs out so much.
They ban people from chat for typing the word "Trap". One of the warframes is literally made to use sci-fi traps and many of the maps/tilesets have traps, so this is ridiculous.
They remove platinum, the premium currency, from players if they receive "Fake Platinum" that a different player hacked in. There is no way for normal players to tell the difference between the real and the fake Platinum, yet the devs will gladly knock your balance down to negative numbers if you get any during trades. Good luck getting them to at least put your balance back at 0.

DE is owned by Tencent aka China now. Stay away.

Last we have the new EULA. Do not spend money on this game. Their new EULA, that you have to agree to if you want to use the game, essentially forbids you from suing them at all and forces you into "Binding Arbitration". DE is owned by Tencent now.
