I'm an elf too. It'll be interesting to see if catering only or a 90/10 split in favour of catering is best with these changes.
It's just that eventually the game gets really boring
I don´t see the connection between getting more troops being good for catering? In the old tourneys the further in the game you progressed, the less catering was an option. At the lastest when you got the 4 barrack levels in Woodelves chapter was when catering became a hobby only, while fighting was what got the job done. I am not saying catering was impossible, it was always an option for people that only wanted to do their FS minimum or 1600 points etc (even though achieving that would have been much easier fighting). With the new tourneys we´ll still have to see how it works out, catering has certainly gotten a little bit more interesting even for high scoring towns, for overcoming very difficult enemy combinations. In my case catering is still less than 1% of encounters, but it is not 0% anymore. In the future I think catering might go up a bit more as I get more used to using that option. i don´t think 10% is a sustainable goal for me, but it might be for others... More than that sounds unlikely. Of course people that catered before should do better now than before I would guess, both because low scored are now easier to achieve as well as the relative bonus that catering got vs fighting. But there is absolutely nothing pointing towards catering being better than fighting now that I can see, it is only less bad compared to before.
If the game gets boring for you, you should try something new! I don´t know, join a different FS, or set yourself different goals, trying playing a new style, if you were catering before try fighting, if you played fast, try slow, if you did tourneys, try the spire (I quite enjoy the convincing game), or try playing a serious adventure, anything that you haven´t done before, might get the interest back up. There are lots of parts in this game... if nothing sparks any interest, I would suggest trying a different game, no point spending your free time on something boring. I guess a lot of people just play for relaxing, then boring may not be a bad thing...
