Dedicated 30 point climbers are only valuable (especially at the Championship level) when they can do so in 20-30 seconds. Most of the dedicated climbers we have seen almost immediately begin climbing taking themselves out of the match opening up the field and for many alliances taking out a very key defensive third pick.
At GSR our team was a dedicated 30 point climber. Our shooter wasn't up to par and slightly interfered with climbing so we took it off. We generally went for the pyramid around 65 seconds after playing defense to allow time to line up and 40 seconds to climb. For Pine Tree we are working to cut that time in half using smarter code so it is valuable for us to dedicate the time to climb rather than score discs. Target is to start climbing at 30 seconds left on the clock but we always can wait longer, score some discs, and settle for a 20 point climb.
