TP only had three actual temples anyway, the Forest Temple, the Lakebed Temple, and the Temple of Time. The rest were a mine, a city, a palace, ruins, and whatever Arbiter's Grounds actually is...
Realistic dungeons... To some extent, I think it would be good. Like what someone said about the hookshot targets, it is a little odd having targets laid around. It would be good if the puzzles and traps seemed to have a reason to be in the dungeon, other than to wait for Link. Snowpeak Ruins was awesome, the place was like actual ruins, and it has cannons and stuff for defence. Why some of the cannons are inside, and all in all don't seem to have range further than inside the ruins, is a different matter. At least they had a purpose.
