You already have a 15 day trial, facebook.
Making a completely open "Try as many times as you like" trial just shows how desperate you are for new players. The game isn't ready for sudden influx's and you're still losing a lot of older players. Either get the tutorial right and be ready for an injection of people or keep trying to build up slowly and sort out why people are leaving the game.
I understand you can't give a free light robot to every new player but honestly when a noob joins and doesn't get help from another player the game is completely ruined and you want to quit. Another change like this and you'll cut off ALL new players from starting the game and it will be down to friends inviting friends.. Which has ended!
If you want to get player feedback don't always listen to what people are Q.Q'ing about. You need to come up with your own ideas. Pitch them to each other and then pitch them to the player base. Even if you make a "Buddy" system that might work better than a trial right now. The market is terrible because there is no NIC changing hands in the game. All the NIc is held by the few rich players and you don't start making a "good" sum of NIC until level 4 and 5 assignments on beta island which most players will never see because of the terrible PVP balance.
TL;DR Bad stuff is happening.
