For anything but PLAYING. Buy a portable 131 wrangle machine and POOOOOF every time you want to buff up you have 131 points of skill more so you can go NR1 any day or be just around 25 levels ahead (25*5) of other guys who didnt want to spend their money ...
New era is coming, era of paying customers who are players of 2nd category and I dont like it. I dont like it so much that it may be the day when i finally decide to give it up.
XP stims, even levels ... okay, but not buffs ...
