Whenever I join on any class I have that has vanq token I end up with 12-15 vanq users.
Whenever I join on any class I have that has prot token I end up with 9-12 prot users.
Whenever I join on any class I have that has conq token I end up with 10-12 conq users.
True story.
Its a stupid system and Im unlucky, but I end up 99% times with such comps.
Or if Im on my warrior as DPS I end up with 5 other dps warriors (6 in raid total), such stuff happens quite often.
On druid had once 9 druids in raid, fun! :P
When it comes to token drops, mostly they drop for classes that are least represented
Summing it up, I never cared for LFR really.
