Shorter, though. Bamboo fills a very special niche: longest 2 slot anti-cav weapon for infantry. A good weapon nonetheless, but their uses are different.
Light Lance is fine for anti-cav too. You have to time it good, but its often underestimated. And after the speed buff a few month ago its a really good infantry weapon, fast and long. I started using it when I was cav a few gens and found it a good inf weapon too (slower back than). Its my favourite weapon now.
