... and so are most people that vote for it.
You really want more? Fine.
The layout of the colony makes 80% of it meaningless in any given round. There is nothing interesting to loot there. Without exception Hydro will always be fortified and fought over. Both LZs are easily breached, but boring to guard. Barrens and t-fort are large, empty spaces that feel like a G-mod sandbox map. 80% of the cave entrances are extremely painful chokepoints. Western caves is never used or fought over because it’s usually a dead-end. North lake is a waste of space that solely exists for marines to flank through when they have already won the round. The Fog Wall is one of the laziest, most contrived ways to "balance" a map I have ever seen in all of my years of gaming.
TLDR: LV is obsolete in terms of design, balance, and aesthetics and the only good reason to vote for it is if your computer can’t handle any other map (you have my sympathies).
There are more gripes I have, but I’ve given you lot enough ammunition as is. Have at it.
