I'd be interested to hear what people have to say, since I'm in a similar boat. I've got about 170-ish to play around with.
If Jagex keeps going with the Bonus XP weekends, another one should be coming up in September. I've been considering stocking up on some resource now (like steel bars or oak planks or something) and dumping it about a week beforehand, before the mass dumps start.
Long ago, the '90s Nicktoons lived together in harmony. Then, everything changed when the century turned. Only Avatar, the best of the 2000's Nicktoons, could save them. But when the channel needed it most, the show finished. Four years passed and Mike and Bryan created the new Avatar: Legend of Korra. And although the show itself is great, it has a long way to go before it can live up to The Last Airbender. But I believe Korra can save Nickelodeon.
