Bro, you mistaken with what has been expressed. It's a change of game play. What do you mean "...giving crap opinions"? The fella is weak in smashes and with 7/10 is under net...Do you really want him to play smashes? What Hideo Kojima suggested was a change in game play. From smashing, try to mix a little with net play or maybe placing shots.

Are these suggestions crappy? It's like learning to drift. There's so many techniques available. If you are not comfortable with power over drift, you can try e-braking, maybe feint drift. I don't see anything wrong with it. It's a matter of preference and change of style. I do agree that being a good badminton player, you need to learn smashing, besides drop shot, back-hand flick or smash, cross court smash so on and so forth.

I'm sure everyone in badminton looking for a fun session. I'm sure meisterlim, devince, or maybe you can share some tips to others as well.
