yeah i guess it's a numbers game... give it another 5 years, maybe the numbers of players trying to implement new skills might be a significant proportion of people playing? who knows.
but i'm pretty sure of one thing.... to make those things work, you have to be REALLY really good at them. not just have a basic ability to execute the skill.... against an opposition that has an ability of say 7 in strong basic skills, you will need an ability of 9 with your less conventional skills to make them work, and almost certainly a matching level of basic skills as well. the number of newer skills with enough grunt to match an opposing basic skill strength for strength are very few, so you need to have an absolute mastery of whatever you are trying to execute to make it work in a hard game... which is probably why we see hardly any of these little things in high level games, as no-one has really reached that level yet. (and it's debatable that they will, while the game remains amateur, and theres only so much practice a player can do)
...point being, good basics are very hard to beat with anything other than corresponding good basics
...or not?
