I didnt think he was trolling, he kinda makes a point, in an indirect and non-helpful way, lol. improving in overall skill will always be good for you, but it should just be understood. thats why "get better" is bad advice, haha.
anyway, counter picking is probably a good idea. counters are going to be WAY more important in brawl than they were in melee because of the more diverse fighting styles and enormous roster and diminished technical skill requiremnt (for now).
for ike, i think the campers are going to pose the biggest threat. against a pit, rob, olimar, etc. i'd definitely switch ike out.
