Bring back test drive mechs and actually change the rotation weekly, give new players a chance to try mechs they don't own yet. As it stands the price of mechs is an insane grind for new users and they can't even try before they buy! If the first mech they buy turns out to be a lemon they probably aren't going to stick around for the 2nd one this isn't good for player retention. I've already seen many complaints from new users when they have to go up against older players that have all the mechs vs their very limited selection of starting mechs.
Also you need to normalize the price of mechs. Some G1 cost 5000 which is fine while others cost up to 25k!. When new players see this they will think the more expensive mech is going to be superior and save up for it, only to be vastly disappointed when they find out its not. *cough looking at you Jobs*. The tears of regret when they realize they could have bought 5 other mechs instead, rage quit this game.
