I understand what your saying about the skills but I still wouldn't go into any game with WE's without rerolls.
My reasoning being as follows:
Leap can be a very useful WD skill; so long as there is a rr to back it up. I wouldn't like to make too many 3+ rolls without backup!
You may need them for vital blocks: you need to create some holes in the opponents defence throughout the game and those skulls will rear their ugly heads!
No surehands. Failure to pick up the ball can be costly at certain points in the game.
Make sure you get the apoth. asap.
Generally I found that initially you don't need a lot of positional players. Not sure about your shorter league but I started with
10 line elves
1 WD
2 RR
FF 8
First buy apoth. then 2nd WD. I've played about 6 games and now have 2WD, 1 thrower with 160k in the bank (TR about 161). I want to get a pair of catchers rather than one (he will be ganged up on!) so that'll be next purchase.
I have been blessed with TWO st4 line elves so far
Anyway, if I were you I'd think again on the rr front.
Hope this helps.
