So this game was fun at first but it's turned into a chore.  Dracula is next to near impossible on hard mode without a proper set up, as literally two hits will kill, some attacks, just one (and these are of course the near impossible to dodge ones).  The solution seems to be farming Valmanway for Alucard or Soma, then using that to kill him easily on the next run, but you have to kill him in the first place to get it, and even then, you're not guaranteed to get one from his treasure drop.
It was fun at first because there was a sense of progression, of going through the levels and getting stronger.  But at this point, it has turned into a grind, trying to collect items/weapons, and it has become clear that the top tier characters are Alucard and Soma.  What's worse, if you want to train as a single player, some treasure chests (specifically, thes ones that you DO want) are simply unattainable without a secondary characters.
The online matching system isn't very good either.  I've had the game drop all players on many occassions, had it freeze multiple times when trying to enter a room, and in most cases it just downright takes forever to find a good group to game with.  No offence to most people, but most players are simply dead weight.  It's fun to pick up and play here and there, but without a sense of progression, it's just one giant grind fest, with no real purpose (since most gamers just farm Dracula anyway--whats the point of farming better weapons when you've already beaten the game?).
I must say I was enamored with the idea at first, but I've become somewhat disillusioned.  The first time a group of 6 tackled Gergoth, it was beautiful, and really fun.  But the novelty has worn off, really fast.
