Why worse? Mathematically there has not changed much for smaller guilds, did it?
Well, the larger guilds got handed a hefty bonus by not paying decay proportionally. So now all a guild has to do is getting as large as possible while staying fairly active to marginalize decay. Any added player with at least marginal activity is a net gain now for large guilds.
While the smaller guilds still are hit by the full 20 accounts min decay. So in proportion to the larger guilds, the smaller guilds were set to the worse. It´s the same effect if you have two kids and you give one 10$ and tell the other "you get nothing". Try this once and watch the reactions.
The same reaction you would expect from the two kids you get in here. The one kid will be complaining why it did not get anything, while the other is full of joy and tells the one kid that got nothing to look out for somebody to hand out 10$ for that kid as well. And the arguments in here are following these very same lowly lines sometimes (e.g. "make your guild grow that big as ours...").
Even from a mathematical point of view the small guilds got the worse side of the system change, There always is an equilibrium where you profit max out of a certain set of rules. Where Bonus against Decay turns into maxed profit. Under the old system if not hyperactively multiboxing to lv. 100 (where max bonus is needed anyway) depending on the calculus the equilibrium was reached anywhere between 9 - 12 accounts as stated several times in this thread so far. The estimates for the new system go into the range of 30 - 35 active accounts. So only from moving the equilibrium point upwards one can conclude that small guilds got the worse of the new system.
While there always will be those that profit from a complex system as the guld renown in DDO, there always will be the loosing side. Switch the rules and those that did profit before now are on the loosing side. But no wonder, take away from the profiteers and they will complain. And that´s what Slarden does here.
And I can understand him very well.
