Dungeon Deserter is a joke...

i queued up for all 4 wings of SoO in LFR. after 40min of waiting i get a Downfall group. once i zone in i notice its a wipe group at Garrosh with around 18 players and no tanks. so i leave group. no way i want to sit around waiting another 20+ min for tanks on a Garrosh wipe group. i would prefer a FRESH zone.

why isnt there an option for joining a fresh raid group? why not tell me how many bosses are killed before i have an option to zone in? why am i getting a 30min debuff because i didnt feel the need to wait around with a failed group on the last boss?

this system is terrible...
