Introducing giveaway drilling event is not totally a bad move. it attracts people to rejoin the game to reap the event rewards. Drilling event as big as this 2 month's gives plenty of incentives for people who have quitted to re-play, somemore its our second anniversary, its worth the celebration, we should just enjoy it. when they rejoin, they will need to get recharge coupons for their driller pets. this increases revenue for the server. giveaways are important because they also make new players feel easier to gain wealth and join the community.
However more can certainly be done.. as mentioned above-giving better quality equips/capes/ face/heads (more dp,md, hp,lk,mp, wt oriented one to help the squishy ones survive) maybe through lvl up gift boxes like the moon bracelet ev to help them through the first lvl 100 can be very effective. they dont have to be too good, the normal ones are somewhat decent.. events should also includes low level who doesnt have driller pets. maybe we can have like a daily attendance, there are such events files dont we, maybe for everyday online they can get like a random monster card that can be used to clear card quests, or to master their skills maybe?
The other way to increase revenue is definitely through selling boxes. just give the players what they desire. and most players want the good boxes.. for example we can release animal boxes(mixing different types), and 1 colour of vivid boxes of all levels every new patch, for example 1 month we can have red, the other month blue, next yellow.. this way we can spread the boxes more evenly and can have more varieties of boxes.
lowering the cost of myshop items to slightly above the current ah value is also encouraged, if there are so much supply in the AH, i am not sure whether will myshop sell any.. if the supply in the ah is running out, people can turn to myshop without paying too much a price. and the quantity in ah will not be the amt you need.
we can also have events that give out microphones like exchanging 100 sarah tix for a microphone so we can spam our tbn and make the chat more interesting xd. or events that gives mycamp furniture/ houses/ gacha coupons so people can spent their spare time to decorate their homes lol? poppuri npc that gives secret cards by exchanging with 6 different random monster cards..just spamming crazy ideas =3=
