I want to share some ideas for our server and little annoyance here and there that i think, one fixed, would make Centurion even better.
1.a. In game shops items should be with pve-like options (ex. + hp/mana or +dsr/zen only);
1.b. Rings and pendants from in game shops should be +0 ;
2.a. I found that "Little Monarch Cloak" and "Small Warrior's Cloak" (lvl1) have greater defence/damage than "Cloak of Death" (lvl 2,5) and it should be exactly opposite;
2.b. Wings in game shops should be only lvl1/small ones;
3. MG scrool "Gigantic Storm" isn't in shop like other skill are, and it should be present.
4. Item "Ancient Statue" from Quest " Extend Merchant Trade" that increase vault storage, is not dropping like it should on losttower 7 from Death Knight.
5. Drop rate for Jewel of Harmony is too high;
6. Elite Healing Potion sold for zen is ruining all kind of pvp in game;
7. HP and damage of goldens are allmost the same be it +1 or + 5 and it should be set accordingly with their lvl.
8. Too many mobs and/or spawn rate is too great. This situation will bring more load to server, lowered frames for players and instability.
9. Arena shouldn't have the highest lvl mobs, because all other maps would be obsolete and unatractive for players;
10.a. Zen drop rate must be lowered since we have excelent items with increase zen;
10.b. Zen tax for move, clear pk, repair should be higher;
11. There is no shields in game shops. For classes that can't wear an offhand weapon like DL and SM that is a little problem;
12. I found that even my Raven hp is low, after reset/sw it restored automatically to full without using the Trainer to heal it.
Probably there are more small issue and/or improving/fixing things that can be done, but i haven't test with all chars/classes.
Maybe other fellow players can bring more ideas.
Have a great day.
