I liked pre-9 Jedi, it kept the population low but I agreed with getting rid of perma death because of some really nasty bugs back then that could get you killed and lose your Jedi. Jedi at the time was also incredibly powerful as well and BH droids couldn't track them so you had to learn the pattern of the targeted Jedi to be able to catch them.
Post pub 9 was when the game started going downhill, the first week of that publish, Theed was loaded with white pajama douchebags dueling TKMs and harassing buffing doctors, but they very quickly became BH's favorite meal. Half a year later, they were a regular sight in any pvp action you'd come across.
In the CU, they were changed again (devs said Jedi with publish 9 was designed for the CU, broken promise?) and were very buggy for the first 4-5 months with broken animation, bugged 3x speed forcerun, exploitable lightsabers, buggy stasis, and a completely useless tree (master healer) but by the time publish 24 came out (the squadleader patch), Jedi was at its prime then 3 weeks later we were hit with the NGE.
After the NGE, it drew the last straw for me and I hit delete on my Jedi without hesitation.
