You know something? The staff is suffering from a bi-polar disorder called Cata-mania. Had this condition been handled monthly/bimonthly using WOTLK-Ray (pew pew gun) treatment, which targets the core system destroying bugs and improper scripts (both pvp and pve), molten would have been THE BEST WOTLK experience one can ever ever ever ever ever ever ever ever have.
Sadly, the psychiatrist said cata-mania is a very strong bi-polar disorder which progresses with time and now its very hard to redirect those WOTLK-rays on a monthly/bimonthly bases. The cells have grown immune to these rays, which, in one case blatantly rejected these rays and destroyed the pew pew gun.
However, recently a stronger pewpew gun called "MIT" was invented which is comparatively way more significant than the WOTLK pew-pew gun, but at the same time very harmful to the environment. The 4th version of this MIT showed clinical significance (MIT-4) to WOTLK (versions 1-to-3rd were only applied on cata on regular bases). The MIT treatment is a tri-to-tetra-monthly treatment which was recently introduced and its main purpose is to target a specific part of the core system in WOTLK. When used on WOTLK, this treatment targets an aggressive side of the core system which goes by the name "PVP", destroying major bugs related to class mechanics.
Why is it harmful to the environment? This is because it introduces instability by lag and some minor scripts that are altered while the MIT rays enter into the system. These instabilities needs some optimization and re-calibration which can take to 2-to-few-days.
For now, this treatment seems to be effective to an extent concerning WOTLK. Hopefully in the next scheduled treatment and the 5th version of MIT (probably November ending), WOTLK will have some core system debugging WRT PVP.
Sadly, a pew pew gun is yet to be invented for PVE core system :(
