As has been said, assuming we could do a 30 pt. climb with limited mentorship and few resources.
Assuming that a mid-field feeder bot was going to be utilized (it wasn't, we ended up playing defense most of our matches, without much pushing power, which didn't do well in the end.)
Accidentely leaving a safety block for our arm in during a match, trying to rotate that arm, then shearing all screws holding it on the sprocket that turns it.
Deciding not to put on an easy 10 point hang that we had with us at competition (I have no idea why...but it will be on for offseason events.)
Attending only 1 regional (We had most of our technical issues worked out by the end of it, but it was too late by then.)
On the back of the one above, not fundraising enough to attend two regionals. (We did do some fundraising, just not $5000 more than what we have had in previous years. We have only ever attended 1 regional a year.)
Going with a tank style driver set-up when we decided to have a kiwi drive (we slipped a whole lot, and it was hard for the driver to control, resulting in too many tech fouls.)
Using too many parenthesis when I write (I mean seriously, who does this?

)
