Badspot had an interesting remark regarding Rising Lava in a Kalphiter drama:
I will consider his suggestions, however they may not all be plausible with climbing.
Yes, let's ignore everyones suggestions and use Badspot's review because his opinion is more valid than five or so other people.
I also found the GameMode more fun when there wasn't climbing. With it, people get too many second chances, without it, it's more strategic that way. Makes people consider taking on another player in an extremely dangerous position.
Edit: Sorry for the agressive first paragraph, but it bothers me when people feed information to someone and it gets disregarded, I absolutely hate ignorance.
