The usual f2p or low casher cannot stack at all his move 1 except for refinements because is not worth it. It is useless to get a 35k power move 1 while leaving move 2-4 to 20k. You will continue to lose to people that did not do like you and spreaded the things, getting one 30k move 1 and 3 25k move 2-4. You begin to get a significative advantage when your move 1 ninja reaches 40-45k over who did not stack, but as i said that thing is not achievable by f2p and low cashers without leaving in the meanwhile move 2-4 at 20k power. That means you get still owned by somebody that did not do like you and spreaded more the resources, ooverall because to take advantage of an high stacked move 1 you need p2w ninjas like itachi susano or naruto ninetails chakra or very hard to get ninjas like kurama naruto.
