erm..
1. bosses seem to have endless specials
2. all bosses are immune to stuns, including stuns from specials
3. no way to immune stun (us)
4. bosses have "unlimited mana"
the boss could still keep healing and casting spells even though its mana bar was completely empty. either dont give them a mana bar, or make them actually work. Its really annoying when one of the two bosses keep stunning, and the other one keep healing.
5. have more items in stores (optional, since not everyone is willing to grind endlessly at training camp to buy everything at low level)
Overall the game is alright, similar to other games of this kind. It is a simple game but it does contain a good amount of things in the game, i.e. the minigames, even though they are simple.
There is also a storyline, which may or may not help keep people playing.
Interesting voice acting. However, this type of game can get repetitive. One good thing is that money are not to make in this game, so not too much time spent on getting items.
personal suggestion for people who plays:
warrior + paladin is a great combo imo. haven't tried anything else, but paladin's wisdom aura provides unlimited mana for warrior's stun locks which works great throughout the game. paladin also have great "AoE" that damages all enemies, and warrior for high damage output.
most importantly, your paladin can heal and can resurrect.
warrior is a good choice for power output mainly because it has skills that can gain some health back through attacking, which is helpful imo if you paladin is busy with something else.
