ive never bought diamonds on here, and get by fine.
diamonds do give you a quicker way of doin things, but its not everything. most important to get anywhere on forge is by putting the time in, some of the advanced players have been playing this game over 2 years, nothing you do will close that gap.
if someone chooses to spend money getting extra things in their city its upto them, their city their playing style.
also alot of the stuff they have may already be won on past events, ive had a rouge hidout since they were first released, so spent no tickets, cups or eggs trying to get them in last events allowing me to use them elsewhere. as have other players who have been here.
premium items are always better, thats why people buy them, if there was no difference then no one would want them, and then we would all probably have to pay to play forge
