I'm just saying once a WA gets block he's not so risky, so adjust your 4-5 skills to 1 and we're fine!
I do agree the negatrait is rather harsh as i've freelanced additional rookie RO's before and lost matchs because of them, however i think the sole intention of WA is to make the big guy a bashing player, the agility of 3 is a luxury i think and though it would be really cool i think the intention of the skill is to guarantee theyw eren't used for passing scoring, etc!
Having said that, WA's are a lot of trouble, i think though that if you keep the must gof irst and just do an apropriate dice roll when entering or starting in a tackle zone or alternatively evening up the other big guys!
Which is what has happened in the league i play, house rules are that NO big guys can have offensive assists, only defensive, thus everything is even i believe!
