Yea there's nothing wrong with interesting (as long as it's interesting, instead, inter/elite rox cos I playz it) chit-chat about theory, I'm down.
I learned alot of skill (weapon skills, art of finding a kill, pixel perfect precision) from playing loads of Intermediate and I feel it requires much more ability to focus than elite.
I developed a really "deep and tactical" eye from playing and watching (I've watched like 400 WEL replays) shitloads of Elites and I feel that Intermediate as a scheme doesn't enable to go this deep and offer the amount of tactical
variety. You really learn how to use the map (controlling chokepoints etc.), limit the moves opponent can do (advanced girder tactics, pushing opponent into certain chokepoint, sacrificing worms in order to get rope advantage etc.) and overall how to be creative about map & worm control since you don't have much utility to use.
There's A LOT of tactical elements in Intermediate also, I just feel that in overall it doesn't offer as much tactical variety as Elite does. Where one might think he's cracked the puzzle by developing a set of "good & safe" tactics (to untrained eye elite might look like this), he simply haven't played enough against very good eliters that actually do everything to make you play their game. There's only a few eliter's whom I consider to have very good tactical eye also instead just good situational based eye. For me, it's not about waiting to opponent make mistakes, it's about forcing him to make them.
Without playing Intermediate I wouldn't be this good in Elite and vice versa. Both are really good schemes once you get to like them. Nowadays I prefer Elite as the amount of focus needed in Intermediate is overwhelming to me (even though I like to play chess).
