As I have started another GBG discussion on the de forums... here my personal set of changes I came up during that:
0) per guild track a guild strength index (GSI)
GSI = sum of all the members' daily attrition values before they are reset)
- for the current season, the previous seasons GSI is valid
1) Get rid of the "leagues"
- the amount of guild power given and other rewards at the end of the season may scale with the maximum LP of the battleground
- all battlegrounds give rewards per battle/negotiation according to the current diamond league reward scheme (having different reward schemes did not make sense from the first day anyway)
- the progress needed to take over a province could scale according to the average GSI of the battleground (maybe going up to 300 or 400 per province, so the large (80 member) guilds have something to do, even when meeting multiple other large guilds)
2) better LP distribution (currently -175 to +175) in the final ranking rewards
- give LP according to victory points (VP)
- the total amount of LP redistributed between guilds could depend on the difference between the most VP and the least VP (maybe in relation to the most VP)
- e.g. when the difference is 100k, a total of 400LP are redistributed (as is currently), when the difference is only 20k, maybe only 50LP are redistributed in total - this allows for a finer spread and also reduces pile-up at 1000 LP
- the amount of LP given/deducted from the guild is proportional to the difference of their achieved VP to the average VP
- this way, e.g. when two guilds totally dominate the battleground, these two guilds get about the same amount of LP, while all other guilds lose about the same amount of LP (with slight variation)
3) reduce impact of siegecamps
- make them act independently (multiplicative) - as was also in jubers suggestion list
- give HQ some base chance to not attain attrition when fighting from HQ - Juber suggested 100%, I personally would go for 50%
4) maybes:
- Juber's soft cap could be used if 2) is not enough to reduce pile up at 1000
- reduce number of guilds in the higher LP ranges if the increase of province progress needed mentioned in 1) is not enough similar to jubers list
- EDIT: as I suggested in this thread before, a system where the player has a chance to get rewards for when guildmates crate progress - the chance beeig proportional to their current attrition level and indirectly proportional to the number of guild members - in this case, reducing the personal rewards to platinum level would probably be fair
EDIT: further proposition:
better ranking
Overall, these suggestions would lead to guilds having similar GSI ending up in the same battleground and GBG would finally be a real tool to determine the top guild(s)
