Like some people already said our problem is that we are getting update made for Korean servers with their needs and desires. But bigger problem is that every next update will be like that also and we will have even bigger problem since they have much better gear and need less xp per level so they are progressing faster than us. Unless @Juji and @Hime make some drastic changes we are in big trouble in future.
We need better xp spots and better gear to catch up with Koreans and even Europeans who already have dragon weapon as average weapon there.
Also big problem is that our game changed from MMO to single player game in last few years and that need to be changed back so classes like iss, tank or healer can be needed and useful again
some of solution could be:
For XP:
XP formula should be changed in a way that players get same xp per mob in solo or pt status, its easy to accomplish it just by deleting part in xp formula where xp is divided by number of party members
Places like fields of silence are crippled since update , they lost 2/3 of hunting spots, this could be solved by adding more mobs to spots or adding more xp per mob and making them party xp zone so more people can farm there.
100-106 isn't bad atm since they can go in coal mines which is amazing place, 106-113 is bad, those places need to get xp boosts significantly if we want to stay even close to Korean servers, if not our future updates will get worse with each one
Adena:
Nerfing IOS isn't good but i would rather see increase in adena drops from regular 107+ xp spots, than insanely boosting spot where only 5-10% people on server can efficiently farm.
In my opinion its better to have 10 people getting 300kk adena per day than 1 guy getting 3b. If average player would get more adena they would be more motivated to buy prestige packs, at the moment people don't buy them since normal hunting spots adena drops are ridiculous.
Maybe people can't afford spending hundreds or thousands $ per month but i am sure 99% of people can afford 15$ for prestige if you motivate them to do so.
L2 Store:
Our store is overpriced, prices need to go down that is obvious to all. Lower prices does not mean less income, cheaper l2 store might attract more people to spend and those who already spend thousands will do it anyway.
Give better deals and you will earn more money for sure. We need those 7 days vitality maintaining runes in store on affordable prices
Other things that need changes are:
Hero shouts its irritating not being able to turn off hero voice. There are times when i go afk and return and all i can see in chat is walls of Hero shouts, petty arguing which shouldn't bother entire server
Overall this update is driving people off server, most of companies is trying to make play time more enjoyable and easier for players except ours, like they want us to quit game.
