In WoT the repairs and ammunition cost money. I only have tier-5 and below tanks, but I can tell you, if I didn't have Premium Time, I could not afford to play my artillery tank all the time and still make any money so I can buy more stuff. I might even lose money on losing rounds after paying for repairs and ammo.
I'm guessing the players who don't buy premium probably do not bang away in an artillery all day because the ammo costs a lot. Maybe this is true of other kinds of tanks that I don't own yet. Either way, it is definitely a way to accomplish two things:
- encourage more class diversity
- give players more reason to get premium time or Hero mechs
I'm not advocating that PGI re-activate R&R. I don't think they have said that they will (or won't.) I just thought I'd mention this as a discussion topic that may affect what weapons and mechs people choose to field.
