Even without reflect the Idol will still be one of the strongest (tank-)pets out there.
Atm I am using the Idol as tank, Stinker as Healer and that Elven Broom as dd (with that most annoying sweep
). My favorite pvp-team now. Has nearly no weakness against the common foes. Of course losing reflect is also a lose in potential damage but then you can get that shield - and it may be even better ... (possibly not, because the "immunity-effect" maybe necessary against various styles and skills).
