I wanted to point out that there is one major fact being ignored here. Just because she will make her own converters do not necessarily mean this would be obsolete.
Geothermal generators accept lava directly now, does that mean the geo generator mkII from powercrystals mod are obsolete? If updated I still plan on using them. You may ask, but why have both when they do the same thing?
Simple, they both generate different amounts of EU. Normals give 10 eu/t where as the mkIIs give 20eu/t.
This is the same argument behind using more than one BC<->IC power converter mod. They may have the same end result, but they do not work the same way. They don't interfere with one another and I for one like having options.
Not having permission is a good reason to pull it, but I see no good reason why permission shouldn't be granted. I really hope she changes her stance on such addons.
