If you are still hunting for a PvP weapon and have to use t13 Titanic clash or even a regular PvE weapon do not worry there are things you can do to accommodate. Titanic Clash is only good for brute force damage. Its' 1 attack speed mods hurts the lancer the most. If this is the only hope of a PvP weapon you have then I suggest you craft conjunct as soon as you can. My preferred choice for lancers climbing the PvP ladder would be to use a PvE weapon with specific stats. Those stats being 2x attack speed, 1 PvP damage, Damage from behind/prone monsters. Behind and prone are also PvP stats; prone being targets knocked down. This set-up gives you the most damage possible against players, as well as getting you used to the 2x attack speed mods
