I'm a new player who spends money on ftp games.  I grabbed the 30 dollar new summon pack, as well as the 10 dollar monthly bonus to xp and money.  Game was starting off good enough, but there are problems that eventually stopped me from playing.  I won't mention minor gripes, but the major gripe that made me say, "No way, I'm done."

Leveling up star ranks

So I love grinding games.  I love grinding for gear drops, grinding money to upgrade gear drops, and grinding for characters.  I also like to spend money sometimes if the game is fun.  I also do not mind sacrificing characters to level up others star rarities.

What I DO mind, is having to level them up first.  Let me explain.

Any good grind game allows you to chart a path of efficiency that covers more than one avenue optimally, or semi-optimally.  You should always feel like you're GAINING something, not losing something.  I'm already sacrificing several 1 stars and then 2 stars, which cost money and items to summon to begin with.  Plus it hurts the collector in me.  But then you're making me lose something MORE: efficient use of my time.

I try to work on more than one thing at once optimally, or as close to optimally as possible.  Early in the game when I have no options, leveling up the dregs to sacrifice means I have to farm several levels lower, receiving less silver and useless gear.  It sucks.  Its boring.  Its one of the worst drags I've had to do in a game in a LONG time.  

It ruins the feeling of progression.  Its like fighting through a tower to get to the 50th floor, then being told to go back to floor 40 for several hours to grind.  Why can't I grind on floor 50?  Why can't I also get some decent loot and silver while I do this?  Ugh.  

And then I think about it for every character I want to level up beyond 4 stars.  So I need to take greens, level them to max, sacrifice whites, then level those greens up AGAIN at 3 stars, sacrifice greens AGAIN, then finally upgrade the character I ACTUALLY want to use to a 5 star character that will reset to level 1...that I need to level again at a lower level area.  HOLY CRAP.

Get rid of needing to level up lower level minions to up star levels.  Its a TERRIBLE idea.  There is already enough grind to work for in this game.  Either that or change how its done.  Drop more beers or improve ways of leveling quickly.  There are a ton of characters, but people want to use them too!  If its this difficult to increase the star level of ONE character, how much time for a full five?  How much time to get a different team or explore the other possible characters abilities and synergies?   No, I'm absolutely done unless a change is made on this.  Perhaps some people find this fun, but for my feedback, its simply too much.
