When I first started playing this game it was worth the $100 to have premium about a year ago on the 29th of this month now you have to spend more than $400 almost every week unless you flat out just purchase jewels to upgrade your tank but it still cost $100 so you're still spending money. I actually uninstalled this game and I've been playing it for more than 2 years. I now play Mech Arena instead because at least I get my $'s worth for $29.95 you get a gold pass.
