it help but you can't rank up only by doing the weekly wintrade like he is saying, it's a perfect nonsense...
He is point we can't rank without wintrading. Nonsense is nonsense.
i expect 400 frontline to be what you need to get ranked 50. it's how players rank it (depend how much you win or loose)
these weekly wintrade of wolfden is just a little boost and don't realy mean people need to wintrade to rank up, it just help a few.
also pvper don't consider this as a grind, even when they reach rank50, pvper continue to play pvp. for the player only doing this for the glamour, it don't help you certainly won't reach your rank.
