Well, on the possible plus side regarding the newly discovered breeds making the lowest ones, at least we now know where the low end tribbles come from and why they are common enough to drop in missions.
The zinc + osol twist took several hours to breed. Maybe server outages or whatever. Anyway I went to K7 in the end. Where better to breed tribbles I thought perhaps naievely. Cryptic really should have put other variables in like location and antecedents as being important, then this would have been a real challenge, not something to be almost solved (except bugs) within a couple of weeks.
Perhaps there should be a tribble patch will make the whole thing rather complex, adding other variables and rendering all previous tribbles sterile due to some klingon genetic experiment to eradicate them.
So do you think the ultimate tribble will be the Roper? and maybe to get it you need all 4 (one yet to be discovered) of the tier 7 tribbles either equipped or in your inventory.
II've been studying the flowcharts, and It looks "Complete" .... the Ultimate tribble would be the unreproducable "Rivera". From what I can see, it would be an offspring of Velasquez after being fed Quadrotricale, the grain from "The Trouble with Tribbles
Break down the name, Quadro.tri.cale (4.3.cale), and doesn't this look like the food side of the flowchart?
