Realm of the Mad God has many cons, and, oh yeah, it has no pros.
The gameplay is absolutely terrible, I hate it along with every other person in this darn world.

An upgrade idea:
Type: Utility
Tier:3(if I'm wrong, the one after always get trades you can afford)
What it does: 10% more trades give value
Another one:
Type: Utility
Tier:4(if I'm wrong, after the more good trades)
What it does: Puts in a "demand" table, which makes certain resources always appear and none other appear, BUT disables other utility upgrades below it
