In my opinion, Jebus-grinding is far worse than SMKA-grinding: the latter we've gradually managed to wean a considerable number of players off of, both on HeroesWorld and on HeroesPortal; the former, in my memory, no one has yet been cured of (admittedly, the time since this infection was discovered isn't that long, but I'm plagued by serious doubts that a cure will be found).
I once had such a period myself. I never played Jebus and didn't want to play it at all. I really disliked the template even just from its description... Then eventually I had to play it once, I really didn't want to, it felt like a complete waste of time. The abundance of free stuff disgusted me, but I still played... Then I forced myself to play it again, and it was already less disgusting; I started getting used to the free stuff and the treasure piles with utopias... Then I played it again, and it seemed almost normal... Then I played it again — I actually enjoyed the game and the free stuff, and by then I was playing nothing but Jebus Cross in a row; then I played it again — great! Then I played it several more times, and then I realized that I really didn't want to and couldn't make myself play any templates other than Jebus, and I only wanted to play Jebus!.. Good thing I signed up for a tournament where I had to play on other templates, and I was forced to return to normal templates; involuntarily, the strong desire to play Jebus Cross began to fade and fade away entirely, and on the contrary, I wanted to play all other templates except it, and never play Jebus again! I never played Jebus again after that...
