MR is not a measure of power, just one of time spent maxing out items. Everyone who has played a long time will tell you not to rush, because it is not important once you learn how to properly mod your weapons and frames and how to run missions effectively. And you'll burn out.
What MR are they? It doesn't take that long to reach the mid to upper teen MR ranks, where you have access to everything MR locked and it stops being as important to reach. I've known a few people from here to do it with minimal help/guidance, and in a active Clan, you can do it much faster. Depending on how much you play and look into the game, you can reach around MR 20 well with in a year playing on a regular basis and much faster if you know what to do, maybe half that time.
Warframe's missions themselves don't change much, and the grind only gets heavier as you go on, but you really didn't see much of the game in the 2-3 hours you played. Unfortunately, Warframe is not a game you are going to want to to play if you don't like or mind repetition to a certain extent. Then again, I really don't know what game you would enjoy at this point if that's the case.
Your gear itself never improves; the mods you use on it are what improve your weapons/frames. Those mods are usable on other weapons/frames as well, so once you max them out and make new weapons, you'll have access to more powerful stuff with different functions. That's when things start to become a lot more interesting. It doesn't even take that long to start increasing the power of your mods to the point they have a much more significant impact on your gear.
It's up to you though if you want to spend your time on it; it is not for everyone for sure.
Maybe you should check out Defiance. That game has more of a traditional MMO loot grind experience to it.







I also asked my friends about the game who have high level characters and they told me that if i want to get to their level, it will take me 2 years hehe.
