Good Evening!
I will like to start by saying i am new and i am just 3 weeks on the server. so here is my so fare opinion about the drop/xp/and zones
Drop: the items drop are let's say decent considering you have also a chance to craft them trough crafting system, also the crafting system should in my opinion get rid of the imprinted items and let us have the normal ones, so we can trade on our alts and also give new players a chance to make some decent adena. about adena drop i must say i want to trow myself from the higher ground, me at lvl 81 and another 4 alts we merely make 1-3 million for 10 /12 h farm. and i must add here you can't really make nice adena since all the spots are over run by players. so literally you fight on one meter square for 2 mobs who are also tough because i have low gear to get higher gear cost me allot and requires loads of nc coins to take a A grade set and weapon.
XP: the zone for xp as melee classes are so few and ones who are are mix with ranger classes who will auto tag so fast you just end up run from one mob to another. and also when you get to kill one you get like 200k xp which bring me to the first line you make absolutely nothing in term of xp per hour because places are few and players are to many. you should make zone specific for melees only. and zone for caster/ranger only in that way you can split the player base and reduce the number of overcrowding. like no idea open the catacombs and let us take rooms this also maybe will reduce the number of pk from heros and the top 2 clans who will kill you for spot just because they need them WL or BH to farm there, which make the game play very annoying by need it to leave. you let character to afk farm for loads of hour just to wake up and see your character did nothing because he was killed by top players for spot. but overall il say the xp is ok if we had more space to farm in pace. but for so much competition is very low.
zones: zone are split in 2 category ranger and melee, both zone are on mix which make the completion for xp very high. one suggestion would be in Curma Tower to maybe add more mobs per square or faster respown rate.in dragon valley i think mobs are ok but in TOI a low b grade titan or c grade WL can't literally farm decent because mobs hit to hard and you need to spam loads of pots. which are also expensive. Also for the zone to be nice split will work to give maybe weapon resist like melee resist for the ranger zones and archer spell resist for melee zone then melee and ranger can farm peacefully. thank you and have a good day!
