This game has great potential but there are a few problems it has:
1. Veteran items make the game far too easy. They scale way too well and once you get the second vet level you can just restart instantly to get the full set, after which gems and gold are worthless because veteran items can't be upgraded or enchanted. Allow veteran items to be upgraded infinitely for a great cost and make the stat increases you can buy worthwhile at higher levels.
2. At the start of the game you can't kill enemies more than 30 levels above you because of the massive damage reduction, but then at later levels you can easily kill things 50,000 levels above yours. The scaling is really off.
3. The Magic Find stat doesn't increase the probability of legendary item drops, only epics. It would be nice if this stat would increase the likelihood of encountering legendary mobs too.
