well… the key arrived too late so i just only can spent 4hours for playing so i dont have much thing to feedback or suggestion here.
my feedback:
1/ Is it only me or my connection just being slow that i often get hit by the boss even i have run out of his attack range. (my fps is about 30-40)
2/ About mini boss in area: he just only spawn in 1 place, this make some players use some heavy object and put it on their attack button while stand next to the spawn place then they can hit the boss and get the bonus silvers/items while afk.
3/ Portal direction animation: yea this, i have wrong this into some kind of quest tutorial lol.
4/ Companion: too expensive while we have to spent silvers for some other upgrade.
5/ I didnt see any auto-party system.
6/ i dont like the animation when holding 2 handed-sword while moving. (it’s looking stupid like Master Yi i think )
my suggestion:
1/ Mini boss spawn in random place.
2/ Change the portal direction animation (?)
3/ Warrior need to have a normal charge attack (holding Z)
4/we need a one/two handed-lance class. :3
5/ Change the animation when holding 2-handed-sword while moving.
i would like to test moar class but dont have much times. 
Can we have a offline version while waiting for a open-beta version ?
And 1 moar importain thing: THANK YOU VERY MUCH.
