As reference by other MMORPG game's upgrade system, I have
the following suggestions:
1.Since the enhancement success rate always decreases with high
updated level which is common in most of MMORPG games. So I think the card choosing is not necessary to the upgrade system. It should be removed and provide a button for enhancement without choosing card which has no actual meaning.
2.Both of weapon and armor should have the same updating rule. 100% update success rate should be available between +0 and +4 only. The success rate of those equipment with upgrade level from +7 will greatly decrease.
Upgrade System:
Here's the references:
Level Success White stone Green/Purple Stone (+2~+3) Downgrade(Max) With white stone Downgrade without white stone
+0 ~ +4 ----- 100% ------- No -------- Yes --------- -0 --------- direct to +0 (50%)
+4 ~ +5 ----- 80% ------- Yes -------- Yes --------- -0 --------- direct to +0 (50%)
+5 ~ +7 ----- 50% ------- Yes -------- Yes --------- -0 --------- direct to +0 (50%)
+7 ~ +8 ----- 40% ------- Yes -------- Yes --------- -0 --------- direct to +0 (50%)
+8 ~ +10 ----- 30% ------- Yes -------- Yes --------- -1 (30%) --------- direct to +0 (50%)
+11 ~ +12 ----- 15% ------- Yes -------- Yes --------- -1 (30%) --------- direct to +0 (50%)
+12 ~ +13 ----- 10% ------- Yes -------- No --------- -2 (50%) --------- direct to +0 (50%)
+13 ~ +14 ----- 5% ------- Yes -------- No --------- -2 (50%) --------- direct to +0 (50%)
+14 ~ +15 ----- 1% ------- Yes -------- No --------- -2 (70%) -------- direct to +0 (50%)
Even we had one wipe while open beta was started, we found that lots of players have full +15 armor until now. Compared to TW / Old version, it is
not possible to be happened even the game was run for almost 3 years.
It reveals that the upgrade system is still too easy for enhancement for cash player. In order to make the game environment healthy, the success rate
and upgrade rule should be changed and make it hard to upgrade even the cash player who cannot acheive +15 so easily.
For Downgrade rule, upgrade with white stone should have downgrade rate as above. The max downgrade level is 2 or no downgrade penalty if upgrade
fails. Upgrade without white stone will downgrade to +0 with 50% chance if fails.
For White stone, it is great to remove broken rule because some effects are hard to generate on the armor. White stone could be used from +4 to +15.
For purple/green stone, the upgrade level should be set as +2 ~ +3 that removing +1. It can be used if the equipment is +11 or below. If you have
extreme luck, you still have chance to upgrade from +11 to +14.
Remove downgrade stone, downgrade the equipment by paying zeni.
Upgradable items:
Main Weapon +0 ~ +15 (glove/stuff)
Sub Weapon +0 ~ +15 (sword/fan....etc)
Armor (Top, pant, shoes) +0 ~ +15
Dogi +0 ~ +5
Upgrade Stone Drop rate:
TMQ > Dungeon > Event > Farming
* CCDB can also get stones from capsule (based on floors).
The above suggestion seems hard to upgrade but it really can decrease the proportional of +13 ~ +15 full gear in the community.
Apart from upgrade system, I suggest multi-client can be limited to 2 as maximum.
