first, i've been playing a lot hours in this game. this game has great graphics quality, combo attacks reward which make player try to get as many combo attack to get many souls and the hard NPC opponent making a lot of hardwork to be badass in this game (i meant to train how to blocks and casts the right spell in the right time ) but this kind of boring game (in my opinion). I found some problems why I considers this game as a boring game.
1. this game lack of in-game reward
for example : there is a leaderboard with many categories, we can know who's the leader of each category but what will we get after being the leader? we'll get nothing? its freakingly hard to be the best 10 or best 100. we need to get some reward for our hardwork. some souls maybe (which can help freeplayers to be badass) and guess the leaderboard need to be reset periodically
2. the crusade battle
honestly, i still don't understand how this work. but as far as I know we can send our champions to invade other's altars but we don't know who is our enemy or how the battle is going. all we'll know is just win or lost. we can't see whether our chosen spells are effectively work or not to be controled by NPC. maybe we need battle report that contain the battle replay, who is the enemy and the result. so we can see which one is the best strategy to get rid of another players when our characters are being controlled by NPC.
3. the way champion is coming while invading
coming as a meteor? and what the hell is he doing after touching the ground? sit? this is being the weakness of the invaders. I'll just cast frozen spell or shock boltz? (sorry I forgot the spell's name) which make the invaders laid on the ground or get stunned overtime which allow us to cast all of our spells out. and when the invaders ready to fight, his Hp is drastically decreased. I think you need to fix this out. maybe when the invaders touch the ground he should be ready to block our attack.
4. is there any chating feature?
I feel kind of lonely playing this game XD
5. the weapons and armors
am I the only one who feels getting great attributes is easy? the price of golden weapon or golden armor are around 40k souls? C'mon, I am lvl 28 and I can get 9k souls in 5 minutes by killing an ogre. maybe another player can get more souls in 5 minutes. maybe you can add some armors or weapons that can only be gotten just by doing the endless dungeon. for example :
floor 15 : white chest I (10% chance to get very very rare weapons or armors)
floor 30 : white chest II (30% chance to get very very rare weapons or armors)
floor 60 : white chest III ( 50% chance to get very very rare weapons or armors)
etc. . .(guess its need several days to get into the sixtieth floor XD)
it'll kind of motivate players to go deeper floor in endless dungeon, and we'll be proud of ourself if we get such a very rare wapons or armors.

so, basicly we need to get another goal beside doing repeatedly quest all over again after transcended. (I ever read the quest will be repeated after transcended) sorry if I have such a bad english (not my daily language). hope you will consider this in future update. :D thanks.
by the way, when do you plan to add the pvp feature? maybe I'll play this again when the pvp released. .
