The only real reason ppl wouldn't want the geode rate increased is because theirs might sell for less.

Considering they added more geode trials as ToM was expanded, i say they should be increased. One time i was blu burning during windsday. The entire windsday killing mass mobs, i had one single geode drop. While i wasn't their specifically for them, it was still annoying.

Availability increase and/or prices drop some would only increase the possibility of players actually doing more ToM weapons. And prices will never drop so low on the higher selling elements (such as wind and fire) that ppl would stop listing them on the AH. Heck theirs a few that are down to 1-2k a piece and their still being listed. So i doubt those currently going for 20-60k a piece are going to disappear.
