Shouldn't need a wet saw. Here's some thoughts, from a guy who's broken plenty of tiles in his time:
1 - Try going real gentle with it. I found if I pushed on the tiles, I'd break them even with the wet saw. If I could go gentle and let the friction of the blade work slowly through the tile -- very little force on the outside -- it worked much better.
2 - Try a better blade. The best blade I have is a diamond-edged metal blade (can't go look at the full name right now, it's in long term storage). I had a 4" blade for my angle grinder that would do anything, but they make larger ones that will fit a table saw.

Um ... ok, I thought I had more good ideas. That's what I'd try. Good luck.
