I have played a pure archer, and I am still able to do decent in melee with a LHB or any other weapon because I got 24 agility and 7 athletics (turn into your hit = get speed bonus). Bounce off is annoying yeah, but with a knockdown weapon or something long enough you'll have no problem killing the average player
Right now you can deal as much damage with 4 power strike as with 7 if you are high agi and turn into your swing, or use your footwork, or use your high amount of wpf for another ability.
This is just a slight rebalancing of agility and strenght, right now agility is worth more than strenght.
