To add to the voice, yes, play KR. Exclusively, in fact.
Ive read tons of posts on dissenting views, but, how many of those are actually from peeps who have tried KR out without being biased against it in the first place? Mindset is a powerful force and Im afraid much of the views expressed against KR is unfair.
When KR first appeared, I actually quit UO, stopped completely, for 2 months, dreading it and the eventual direction UO is going(to implement KR totally eventually. Well, at least it was that direction then). Then, one fine weekend which I know is totally free of RL stuff, I finally got the courage to install and patch KR. Really spent the weekend reading up on the Stratics KR Forum and the possibilities, applying the knowledge, and tweaked the nine heavens outta this "semi"-finished product. When I finally got an inkling of a working setup for my tamer, I kept going to make it finer and now, Ive a complete personalized setups for all my chars. Never looked back since.
I sincerely hope this would inspire anyone who read this out there to just keep an openmind and try KR out just for the heck of it. I know some of you have been in 2D for years and years. Why not try out a familiar game with a fresh perspective? Who knows, u might come to like it ^^. And when the critical mass is reached, the final transition to a "fully-certified" KR may come to fruition.
