Honestly, PVP is a lot more than mashing W, spamclicking, and jumping. The 1.9 update, without any modifications by Meepcraft, will, as legendcaleb said, turn into a turn-based game. I wouldn't be opposed to 1.9 if the clicktimer was removed or even lessened, but as of now:
1) God armor would be devalued, and people who store their fortune in god items would become broke. Thus disenfranchised, they'd be more likely to quit, driving valuable potential donors away from the server.
2) God fights would take FOREVER, making terrarium useless. Furthermore, fights would basically be determined by chance. Mastering strafing, w-tapping, etc. takes a lot more practice than hotkeying effectively to the most damaging weapon.
3) Hackers would be a lot harder to catch. Most hackers are caught when their hits are erratic and their head snaps dramatically. With a click timer, hacks would be a lot easier to hide, and the staff team would have a difficult time removing hackers with any sort of accuracy.
