few things missing that add a lot of fun to the game refining, gemming, casino survival games, and lotttery.
How about this one, gives incentive to level, puts new items in game, provides risk and entertainment, appeals to both grinders and bossers, expands the quest system.
Expand the crafting system. this just an example
At level 15 there is a quest chaiunn which ultimatelyends up with being able to choose 1 of 3 professions.
1 - Armourer - can craft armours, boots helms nbelts.
2 - Smith - can craft weapons (they are biggest source of stats from a single item so limit this profesion to just weps)
3 - Jeweler -can craft ring, brace and necklace.
Each profession has a number of different ranks allowing player to craft different tier items. Each new rank can be achieved with a quest chain at a set level. for example, rank 1 is lvl 15 at 25 can move to rank 2 and at lvl 35 can move to rank 3.
The items will have a certain chance to fail when crafting so is a gold sink, there is risk to it liek refining and gemming, and gives the items crafted some value for sale.
The materials for these items will drop from normal monsters throughout mir. A different material or set of materials from each cave/area. For example, psc drops iron shard, zt drops leather scraps, and bug cave drops crapace. Meaning you would have to hunt psc and zt for materials to make a steel armour, or zt and bug cave to make carapace armour.
for each tier of crafting have a masterpiece item that requires rare materials that can be obtained from a boss of that level bracket, so tier one would be wt khazard etc, where as tier 2 would be ec etc etc.
this means boss players can enjoy hunt bosses even if they get **** drop they got materials they can use sell. Grinders can grind and if they dont get item drops they can sell or use the materials they found.
So alongside this extra incentive to hunt, the influx of decent new items, the new quests, the excitement of a gamble and the gold sink. you have a system that provides a benefit for all type of player and probably create a new one as im sure thered be ppl willing to sit in town crafting there asses off to make a decent profit, and also keeps ppl from being bored.
