I don't really get the build "variety" of Souls either. It doesn't really matter if you use like a katana or hammer really; one is faster and gets more hits in doing less damage per hit vs slower with less hits but more damage per hit (and both probably net the same DPS). In Souls, you basically just dodge (or block) and then attack until out of stamina regardless what weapon you're using. Bloodborne did make bigger weapons feel different where you can smash an enemy to the ground with charged hit but then the enemy has invincibility frames getting up (and your character doesn't) and basically defeats the mechanical purpose but it looks good at least. And other playstyles are really underwhelming (in feel) like magic or the bow and arrow, there's other games that do those so much better.
