The other CP rewarding nodes in PVE - the 4 essential and the hardest node - both give us 2 CP in the rewards for a 48 hour sub. This was done so that players would keep the same CP income level even if the other rewards (iso and tokens) are slowed down by having a 48 instead of a 24 hour sub. However, the 5E only gives the normal CP amount one time regardless of whether it is 24 or 48 hours.
It would be a nice change to reward the CP - 1, 2 or 3 depending on SCL - twice in the node rewards when we play a 48 hour sub. To me, the 5E is a reward for rostering and leveling a 5*, as well as a fun challenge. A little more recognition of this would be appreciated.
Many people have asked about this and the player base would be very happy if this was changed.
