The encyclopedia in Sanahtlig's toolbox gives you a quick peek on all the upcoming Hime, if you ever want to know what some character can do.No it's not. Although some mechanics in DP are fun, such as doing Conquest with friends, you'll quickly tire of the P2W nature of the game. Just look at the current events - count how many of them are just adverts for "gib moni plz kekekeke"
You can do what Gilmok said above you without paying a cent (assuming that you can find a good Guild or organize one to do well in Zodiac events), but often enough your entire Guild gets soloed by some P2W player. He'll just buff up, hit the boss once, overkill it for 7483274893274802374 trillion damage, aaaaaand all your hard work has been for vain.
