I just started playing this game again after a LONG break following a few changes which I disagreed with. In an update about 3 years ago OOO changed the monetization scheme from Mist + Crystal Energy to the more standard free to play system we have now. For the most part the new system is alright, however you have to jump through hoops to heat your gear and the cost of buying the materials needed to upgrade a weapon more than tripled (to be fair under this system it is Possible to be a true free to play player where it was not before however the amount of grinding needed is INSANE). I'd love to see this reconsidered, though I can live with the way it works now. However I feel this game lost a great deal more with the other change. Players can no longer share HP to revive their allies. This change was the worst mistake I've seen any game company ever make. A great deal of the fun to be had in this game was juggling those last 2 or three hits between players while tackling the hardest content. That's not the extent of what was lost here though. This change alienates newer and less skillful players since you only get one chance at the level before you're out, where before if you ran with some more experienced friends they could carry you though levels and give tips on how to get better at the game. It's just sad playing in a public lobby on tier 3 people seam to join then die twice and leave in frustration. I sincerely hope that we can share HP to revive again sometime -> the game just lost too much when it was taken away.
Just figured I'd post my thoughts since coming back. I wonder if anyone else feels the same way...
The update that you're talking about is 2013-07-30. We've had many threads lamenting the loss of the HP revive. So, yes, other players feel the same way. Cheers.
