To all those who are complaining about not having enough chakra to keep with all the group summons, they did add Group chakra packs to the group store to help remedy this:

"Group Shop updated: Group Points*500 can exchange Group’s Summon Chakra Pack*5"

While this isn't a perfect solution to the problem, it means that one group member, if they don't have anything else to get in the group store, can get an additional 20 chakra packs a week not including what they can get out of SA if they are on a dead server and its not a XGNW week. At least there is some thought going into some of these updates.
