well... if you do the very light training... than you don't need green pack.... but even the problem is everytime i did that, i lost the next match....i lost 2 league even my team is the better Q like Q 68 vs Q59 -60.... and both lost 3:1 ..... but when i just a very hard training (use more than 50 green pack) ... i won the match ... in the CUP, i won 6:0 facing LV 10..(i am LV 9) with the same Q, 7 stars as my team~
and also, the 3 hr recover rate for 6% is still too too too low~~ i just did 5 drill in one training ...already take 12%.... and that need 6 hrs.... and if i have 3 matches a day.... how can it works??? (as i said i did the light training...just 2-3 easy drill in one training( and need two section for better preparation)..and i lost all the following games...)
