To hell with the economy. Here's how I'd fix the site;
1. Fix the lag. They have absolutely no reason to still be lagging after 10+ years.
2. Force ads to be silent. Or better yet, get rid of the ads altogether. I use adblock, but for those too inexperienced in the internet to get that, this is a must.
3. Change restocking so items like SuAP actually restock, despite dupes and whatnot holding them back.
4. Hire a writer who isn't stuck in the 1st grade fantasy book mindset. I mean, they're just animals and not people, but a good story every so often wouldn't hurt.
5. Personal preference, but Mixed Paint Brushes by combining two at the cooking pot. Imagine; Darigan Grundo with split color, or a white Maraquan Shoyru. A little photoshop work can do the recoloring easily and in a few seconds. I know people would like recolored mutants, too.
