Those are str builds
Just pointing out that they work very similarly to two handers with str builds damage wise, a hit to the head will almost always get a kill, a body shot will do a lot of damage, sometimes kill. Main difference is your trading off a little bit of extra range and the ability to avoid parries and chambers, for very increased likelihood of missing, opening yourself up to be hit easily, an you only get 1-4 opportunities to kill instead of an unlimited amount.
As they are now, the only thing lances are really great for is anti cav, other than that, stones are a better choice.
After all most people are using them for lulz because it's clear those are OP.
When something is obviously OP, its not for the lulz that people use it for, they use it to dominate the battlefield (i.e. the barmace craze when it was fast and had crushthrough and knockdown). People use things for the lulz when they can occasionally get an unlikely kill and cause someone to go rage on the forums about it.
