No. Rangers aren't good for team composition in both WvW and sPvP. Unless you're running a druid bunker heals, even then, other classes do that job better, like Tempest, FB, Chrono. Ranger is acceptional and extremely broken for small scale. 1v1, 2v2, 3v3, etc. High burst damage with unblockable attacks and channeled abilities, makes them scary in small scale fights/roaming.
