And here I was asking if I was modifying my numbers too much, yours are huge compared to mine! Thanks for your numbers as they're a good way for comparing. I think I'll try editing the file and see how it goes via LAN. I really don't want to change it that much in the end, just trying to have a more interesting and faster progression.
PS: Did the tweaking on balance.txt, after which I ran a level 1 High Elf to get the quest and kill values in both Bronze and Silver. Then I ran my level 115 Shadow Warrior on LAN and made the Runemaster's Son quest. Here are the changes and results.
TWEAKING:
MP_experience = {1000,1150,1325,1550,1825}, => MP_experience = {1500,1150,1325,1550,1825},
QuestExplow = {20,25,30,40,50}, => QuestExplow = {30,40,45,60,75},
QuestExpmax = {4020,5025,6030,8040,10050}, => QuestExpmax = {6030,7540,9045,12060,15075},
ExpLS100 = 985, => ExpLS100 = 1015,
ExpLS125 = 980, => ExpLS125 = 1020,
ExpLS150 = 975, => ExpLS150 = 1025,
ExpLS175 = 970, => ExpLS175 = 1030,
RESULTS:
BRONZE
QUEST XP: 20 / 30
ENEMY KILL XP: 14 / 21
SILVER
QUEST XP: 25 / 40
ENEMY KILL XP: 17 / 25
SW LV.115
QUEST XP: 6381 / 9572
ENEMY KILL XP: 2638 (champion->5578) / 6394 (champion->13521)
So this is it. The ratio of 1.5x the base XP gain seems well in order, and the progression with the post level 100 boni instead of penalty is definitely noticeable! I mean, a regular mob now gives more XP than a champion unit with the base XP gain. It's a 2.42x ratio of XP gain at level 115 (though in all honesty that SW has XP gain socketed so the ratio should be smaller). I think this might make the levelling more rewarding past level 100 since millions and millions are necessary to level up. What do you think? Is this a balanced way to get closer to 200 in a more productive amount of time?
