ARR also had a lot of rushed parts because they were trying to recover from the critical disaster of Legacy. Whatever good points it may have had (I wasn't there, I can't judge), 1.0 was a complete failure in business terms, and ARR was under huge pressure to fix it. So there was a lot of throwing things at the wall to see if they'd stick. We can see from guildhests, battlecraft leves, the MSQ roulette, and the higher difficulty tuning of the Binding Coils, among others, that quite a few things didn't go as planned.
