GW is B2P with no monthly fee, so no not like WoW.
War is B2P with a monthly fee, like WoW.
------------------------
Not too much experience with War so not gonna say anything about that. But GW has no grind and very little lvling, u can hit max lvl in like a day or 2. Or u can make a PvP char which is no PvE and purely PvP and it starts out at max lvl and u unlock gear/skills by pvping.
