I agree. There are far too many legendary weapons and mechs. What will happen to the new players? Nothing, because they can't get any further. I know a lot of people who have uninstalled the game because they don't make any progress. 

We are currently dedicating our efforts to developing Mechs and Weapons for the endgame—the most advanced and ultimate stage of Mech Arena—designed to offer players the highest level of opportunities and experiences.

I know, I understand it too. But you are losing a lot of new players! Players who will definitely buy something with real money but who might want to test the game first. But suddenly They see that you have to spend money to make progress. And they uninstall the game. 

What I'm saying is that if you keep going like this, hundreds, no thousands of players will leave the game. 

And that would really be a shame.

Like I said there are way to many legendary weapons plus it's hard to reach endgame. Most players get stuck early to mid game so we need more midgame weapons which are epics and rares. My midgame hanger has loads of legendary weapons and I don't think midgame players are supposed to have that many. Just add or swap over some legendary weapons and mechs to epic,reduce the damage and maybe you'll get less complaints about matchmaking.
