Sure, that's a good idea to use extra contribution points on group wheel. Even better now that the rewards are better than before.
Depending on group level, can spend 500-600 points/day. And can get contribution point from convoy/plunder, donation, group trial and gnw. Besides the higher the group level slower is the progress to unlock the next set of group skills.
In short, there is no reason to not do them.:)
PS: - Started spending my extra points this way since before the update. Wish I had my points saved now, could have gotten better rewards. Oh well.
